552. Follow up on pug with urinary stones operated twice - SD diet, no choice

At 7pm, the young lady working in the clinic who keeps only pugs as pets came for her S/D canned diet. "My pug has been taking for over 6 months, she said. "No choice. She already had two bladder operations to remove stones, the last one was under you.

"When I give home-cooked food and meat, the urine becomes cloudy and discoloured. When I give S/D, the urine colour is clear."

The pug is in excellent health.

ADVICE
1. To collect urine sample for analysis of struvite crystals and change to C/D. She will bring the pug downstairs and catch his urine. She has her own urine collection bottle.

551. Auditing Veterinary Spays at Toa Payoh Vets - Key Performance Indicators

KEY PERFORMANCE INDICATORS FOR SPAYING A HEALTHY AND YOUNG
FEMALE DOG AT TOA PAYOH VETS

Key Performance Indicators (KPI) should also be applied to veterinary surgeries as in any other businesses to improve the performance of a practitioner, to be operationally efficient and reduce wastage of veterinary materials used. A shorter surgery means lesser risk for pets undergoing anaesthesia.

From 2011, I will be monitoring the time it takes for a vet spaying of a female dog in Toa Payoh Vets and to do that, I have had recorded two spay cases done by me in 2011.

How long does it take to spay a female dog without complications? Two cases done by me are illustrated.

CASE 1.
Fox Terrier, Female, 1 year, 9.3 kg
Last heat 3.5 months ago. Skin incision 1.5 - 2.0 cm long. Spay hook is used. No subcuticular or subcutaneous sutures as they do irritate the dog. No IV drip set up.

CASE 1. SPAYING THE YOUNG FOX TERRIER
1. Time when the dog is given Domitor + Ketamine IV*. Atropine IM (A) = 2.29pm.
2. Wait 5 minutes. Isoflurane + oxygen gas in mask. Intubate.
3. Time when the skin is incised (B) = 2.35pm.
4. Time when the skin is stitched (C) = 3.01pm.
The following key performance indicators are as follows:
C - A should be less than 35 minutes.
In this case, C-A = 32 minutes.
C - B should be less than 30 minutes.
In this case, C-B = 26 minutes.
No. of suture packets used - one packet 2/0 absorbable
No. of stitches to close the linea alba - 3 simple interrupted
No. of stitches to close the skin - 2 horizontal mattress
Skin incision 1.5 - 2.0 cm


DOMITOR + KETAMINE IV WITHOUT NEEDING ISOFLURANE + O2 IN HEALTHY YOUNG DOGS
At 10kg bodyweight, Domitor = 0.4 ml. Ketamine = 0.5 ml. Total = 0.9 ml in one syringe. Give via IV.

If the above is given at 50% of the calculated dosage, isoflurane + O2 top up for less than 60 seconds, to effect (eyeball rolls ventrally and other signs) will be needed. Intubation is needed. Atropine IM is advised before surgery. Antisedan IM after surgery may be useful to get the dog to wake up within 2 minutes.

Fox Terrier, 1 year, Spayed. Rigid limbs after giving antisedan
to wake up the dog early. Atropine was given to resolve the problem.

CASE 2.
Shih Tzu, Female, 9 months, 5.3 kg
lst day of heat. Skin incision 1.5 - 2.0 cm long. Spay hook is used. No subcuticular or subcutaneous sutures as they do irritate the dog. IV drip is given before injection of sedatives.

1. Time when the dog is given Domitor + Ketamine IV*. Atropine IM (A) = 3.15 pm.
2. Wait 5 minutes. Isoflurane + oxygen gas in mask. Intubate.
3. Time when the skin is incised (B) = 3.23 pm.
4. Time when the skin is stitched (C) = 3.41 pm.
The following key performance indicators are as follows:
C - A should be less than 30 minutes.
In this case, C-A = 26 minutes.
C - B should be less than 20 minutes.
In this case, C-B = 18 minutes.
No. of suture packets used - one packet 2/0 absorbable
No. of stitches to close the linea alba - 3 simple interrupted
No. of stitches to close the skin - 2 horizontal mattress
Skin incision 1.5 - 2.0 cm





4411 - 4416. Spaying a dog at her first day of bleeding







How long it takes to spay a female dog?
Injection of sedative to skin stitched up
Skin incision to skin stitched up
Case 1. The Fox Terrier, 9.3 kg. Isoflurane gas top up needed. Domitor 0.2 ml + Ketamine 0.3 ml IV. Approximately 50% of the calculated dose was given. Calculated dose should be Domitor 0.37 ml + Ketamine 0.47 ml IV would not need isoflurane gas top us
32
26
Case 2. The Shih Tzu, 5.3 kg. No need isoflurane gas top up as the calculated dose is given. Domitor 0.2 ml + Ketamine 0.25 ml IV.
26
18
If there is no need to top up with isoflurane + oxygen gas, the time taken from skin incision to skin stitched can be as fast as 18 minutes since there was no time wasted in topping up the anaesthesia and the hooking out of the ovary can be successfully done within 3 hooks.

Injectable anaesthesia in the healthy dog and cat
in one syringe. Calculated dosage for healthy and young dogs and cats
Weight & Health Status
Domitor
Ketamine
10kg healthy, young female dog
0.4 ml IV
0.5 ml IV

Domitor 5-40ug/kg = 0.005mg/kg-0.04mg/kg
Ketamine 2-5mg/kg
Heart-diseased dogs - Do not use domitor + ketamine. Old dog - Use less domitor or 50% of the calculated dose. I will just use isoflurane + O2 gas solely if the dog is in poor health rather than taking risk with Domitor or Domitor + Ketamine IV.

Domitor and ketamine are synergistic and their combined use will be safer if injectable anaesthetics are required and no isoflurane gas is available. For healthy young dogs, use the calculated dosage given above. For heart-diseased dogs, use 50% of calculated dose and give isoflurane gas top up. Do NOT use domitor + ketamine is heart-diseased dogs.
I have around 30 years of small animal practice. I founded Toa Payoh Vets in 1980 and it is 2011 now. So practice makes perfect. The faster the surgery is done, the lesser the anaesthetic risk to the dog. So, I will be auditing veterinary surgery done by myself and vets at Toa Payoh Vets from 2011 onwards.

How to successfully toilet train an apartment puppy in Singapore?

Thank your for your e-mail. My reply is in CAPITAL LETTERS/


On Tue, Aug 16, 2011 at 10:57 AM, ...@yahoo.com.sg> wrote:

Dear Dr Sing


My family had gotten a 8 week old sheltie puppy for a week now. This is our first time. I have been trying to toilet train it but not sure if I have done it correctly. I have spent a lot of time reading up from the internet but the more I read, the more confuse I get and fear I have done it wrongly. I was so stress and frustrated until I saw your blog. It is so comforting to know there's someone who actually address puppy training problem that is relevant for Singapore pet owners. Thank you so much.


I have attached a picture of how I confine the puppy. I confine the puppy in the play pen most time of the day.
CORRECT WAY


I noticed that it will pee on the pee pad but not 100% of the time. Sometimes, it will pee on the boundary of the pad and a few times on the tiles.
BLADDER CONTROL IS VERY POOR FOR 8-WEEK OLDS.


Every time it pees on the tile, I would quickly soak up the urine and put the tissue paper on the pee pad with the puppy then proceed to clean up the area with odor remover. As for poops, it will also poop on the pad but sometime on the floor.


MOST COMMON SITUATION IS THAT THE PUPPY CANNOT POOP ALL AT ONE TIME DUE TO DISTRACTIONS FROM THE OWNER, THE OWNER'S CHILDREN, FRIENDS AND PARENTS WANTING TO PLAY WITH HIM DURING MEALS. SO, IT POOPS A BIT AND POOPS SOME MORE LATER. THE PUPPY SHOULD BE LEFT ALONE DURING FEEDING AND ONE HOUR AFTER FEEDING, BUT THIS IS SELDOM POSSIBLE IN BIG FAMILIES. A COUPLE WITH A PUPPY IS MORE SUCCESSFUL IN TOILET TRAINING.

Beside using the pee pad, I had a pee pan with grate which I had tried using. I noticed the puppy will sometime pee on the pee pan lined with pee pad but not always. It even lays on it sometimes. And if I put the grate on, it is more difficult to get the puppy to pee and poop on the grated- pee pan, even when I lined it with pad or left some urine on the tray. So now I removed the pee pan away and waiting to see how my puppy reacts.

YOU ARE CONFUSING THE PUPPY. IF YOU USE PEE PAN + GRATE, THEN USE IT. IF YOU WANT TO USE PEE PAD, USE IT SOLELY. IN ANY CASE, 1 WEEK IS TOO EARLY TO BE SUCCESSFUL. THE BEST WAY IS TO KNOW HOW THE PUPPY WAS HOUSED AND ITS TOILET HABITS AT THE SELLER'S PLACE BUT THIS IS USUALLY NOT KNOWN.


I do not confine the puppy 24 hrs in the play pen. I would let it out into the house with supervision. During these time, the puppy would sometimes pee on the floor even when our eyes are on him. He is simply too quick for us. One thing I noticed is the puppy does not always as predictable as describe in most articles. It doesn't always poop shortly after eating. Sometimes it will stay alert for a while and go to sleep after eating without pooping.
EACH PUPPY IS AN INDIVIDUAL. ALSO TOO MUCH DISTRACTIONS FROM YOU AND FAMILY. IT JUST CANNOT GET A ROUTINE OF PEEING AND POOPING AFTER MEALS SINCE HUMAN BEINGS ARE ALL OVER THE PLACE, FUSSING OVER IT (I ASSUME THIS IS THE SAME SITUATION FOR YOUR PUPPY).




During the first two nights, the puppy actually woke us up because he pee and poop in the pen.
COMMON OBSERVATION BY NEW PUPPY OWNERS. THE PUPPY ASKS FOR CHANGE OF SOILED AREA


Then I resorted to sleeping in the living room to monitor him. For two nights, I woke up to put him on the pad to pee. There was one night I actually didn't set my alarm on purpose and managed to sleep through the night waking to find the puppy only pee on the pad.

SUCCESS IN TOILET TRAINING TAKES TIME AND PATIENCE, NOT JUST 2 NIGHTS. IT TAKES 2-6 WEEKS DEPENDING ON THE OWNER AND PUPPY.

That gave me much encouragement! However, that was the only time. Subsequent nights, I woke up every 2 hrs to put him on the pad and pee. Then last night, the puppy pee and poop on the tiles before my alarm went off.

STOP WATER DRINKING AFTER 6 PM. FEED DINNER EARLIER AND LEAVE THE PUPPY ALONE ONE HOUR AFTER FEEDING.


I also want to know can the puppy be trained to pee and poop outdoors if he is being trained indoor now.
CAN BE TRAINED OUTDOORS BUT TAKE TIME AND PATIENCE AND A ROUTINE TOO.

I was told not to bring the puppy out before all vaccinations are given.
THIS IS TO PREVENT INFECTIONS BY DEADLY VIRUSES



Besides the toilet training part, I also read in your blog that handling puppy at this young age must be gently so as not to leave an imprint of fear in it. Now I am very worried because I had hold him on the floor when he tried to bite my hands during the first two day he came. I might have also caused him some stress when I tried to pull him with a lease once. How ignorant I was and why didn't I found your blog earlier. Will these experiences last forever in the puppy? What can I do to undo the damages I have done.

TRY USING POSITIVE REINFORCEMENT METHODS OF TRAINING - PRAISE, TREAT AND PLAY FOR SUCCESSFUL OUTCOME. CLICKER TRAINING PERHAPS?.


I hope Dr Sing you can help me with my puppy as I am really very stress and worried because I don't know if I am doing it right even after doing so much reading.

NO TWO PUPPIES CAN BE TOILET-TRAINED IN IDENTICAL METHOD AND BE TRAINED WITHIN THE SAME PERIOD OF TIME ESP. IN HOUSEHOLDS WITH LOTS OF FAMILY MEMBERS. CONFINEMENT, CHANGE OF SOILED AREAS, POSITIVE REINFORCEMENT TRAINING AND PATIENCE AND TIME ARE NECESSARY. SOMETIMES NEGATIVE REINFORCEMENT WORKS TOO DEPENDING ON THE PUPPY'S PERSONALITY. IT MAY TAKE 2-6 WEEKS TO TRAIN SUCCESSFULLY IN AN APARTMENT.

549. Was the puppy vaccinated too early?

Dear Dr Sing


I have emailed you under the subject 9 week old sheltie puppy. I need you advice on another problem regarding vaccination. My puppy was vaccinated between 4th and 5th week by the breeder. The second vaccination was scheduled this Friday 19 Aug when the puppy is 9 weeks old. The problem is two or three days after I brought the puppy home, I brought him to a vet near my place because I found a tick on the puppy, at the same time also to consult the vet on bits of blood stain in mucous found when the puppy poops. The vet prescribed antibiotic, probiotic, kaopecin, spot on tick remover, deworm tablet for my puppy as treatment,and advise on cutting milk powder from its diet. During the consultation, the vet mentioned that the puppy was vaccinated way too early and I should postpone the 2nd vaccination till the puppy is 3months old. I am not sure if this was proposed because the puppy is under treatment or just to put the vaccination back on schedule.


I called up the clinic that did the 1st vaccination for the puppy and was told that they allowed vaccination for the puppy at 4-5 weeks old after examining the puppy to be health and the puppy was considered of good size, so no problem for that.


The puppy is fine now with firm stools except for the spot on tick remover which I will be applying tomorrow.


Could you advise me whether to proceed with the 2nd vaccination as scheduled by the vet who did the 1st shot or listen to the vet who treated the puppy for tick and soft stools.


Thank you

E-MAIL REPLY FROM DR SING DATED AUG 17, 2011


Thank you for your e-mail. It is difficult to advise as each puppy's immune status is different.
It seems that some vets in Singapore and in Australia have their own recommendations. I have had seen Australian vets recommending vaccinations more than 8 weeks after the first one.

Much depends on the disease situation and immune status of the puppy and whether the dam has had updated vaccination.

My personal recommendation for puppies bought from Singapore breeders (in Pasir Ris) will be a booster vaccinations 2-3 weeks after the first one. This is based on the vaccine brand I use and on this vaccine manufacturer's advices. 3 vaccinations are advised for the puppy.

In your situation, I cannot be more specific as much is unknown about the origin of your puppy and its updated health status. Therefore, you will need to take one of the vet's advices.

KEY PERFORMANCE INDICATORS FOR SPAYING A HEALTHY
FEMALE DOG AT TOA PAYOH VETS

How long does it take to spay a female dog without complications? A case is illustrated.
The answer is around 26 minutes from skin incision to the end of stitching.
The whole process from sedation to the end of stitching is 31 minutes.

A case spayed by me as an example:

Fox Terrier, Female, 1 year, 9.3 kg
Last heat 3.5 months ago. Skin incision 1.5 - 2.0 cm long. Spay hook is used. No subcuticular or subcutaneous sutures as they do irritate the dog. No IV drip set up.

1. Time when the dog is given Domitor + Ketamine IV*. Atropine IM (A).
2. Wait 5 minutes. Isoflurane + oxygen gas in mask. Intubate.
3. Time when the skin is incised (B).
4. Time when the skin is stitched (C).

The following key performance indicators are as follows:
C - A should be less than 35 minutes
C - B should be less than 30 minutes




No. of suture packets used - one packet 2/0 absorbable
No. of stitches to close the linea alba - 3 simple interrupted
No. of stitches to close the skin - 2 horizontal mattress
Skin incision 1.5 - 2.0 cm
DOMITOR + KETAMINE IV WITHOUT NEEDING ISOFLURANE + O2 IN HEALTHY YOUNG DOGS

546. Sunday's interesting case: A 3-legged dwarf hamster with 3 warts

Tuesday Aug 16, 2011, 9.16pm typed at Toa Payoh Vets

As the owner's "hamster" vet was not free to operate on the hamster till 2 weeks later, the practice's other vet asked the owner to bring the hamster to Toa Payoh Vets. Some vets would just give oral medication but it would not work to get rid of the 3 warts.

I answered the phone and took over the case when the two ladies came. The hamster looked thin. "Very itchy, esp. the left hind thigh; it is just a stump; there is no leg."

WARTS. As the hamster disliked being handled and protested vigorously by squeaking, we could not examine her in detail. Two warts were seen. One on the front right fore leg and another one on the left thigh area. Actually there was a 3rd one seen later under anaesthesia

ANAESTHETIC RISKS. As the female, over 1-year-old hamster eats "very well," pees a lot and poops a lot, the hamster was deemed to be healthy. I warded her overnight for observation and gave oral antibiotics and anti-inflammatory. I gave a 60% chance of survival.

RECURRENCE OF WARTS. If sufficient normal skin is excised with the big wart, it is unlikely to get recurrence. But there may be a large skin wound which would expose muscles and bones, causing infections. This was communicated to the owner.

EXPOSURE OF BONE AND MUSCLES. If the wart has no stalk, it would be a bigger skin incision exposing the bone and muscles. There could be infections and gangrene. The owner was informed.

ELECTRO-INCISION WOULD BE THE BEST.

SEDATION USED
Monday Aug 15, 2011. Heavy rain. The hamster cleaned up its food bowl. Actually she stored all seeds inside the cheek pouch. However she was active and stool pellets were seen.

10.38 am Zoletil 50 x 2 drops IM, right hind muscle (left hind has wart). Usually I do it on the left. 54 g bodyweight. 1 drop would be insufficient. 2 drops would be just right. Two drops equal to 0.001 ml as the drug did not even reach the 0.01 ml mark in the 1 ml syringe. I pull in 0.08 ml of normal saline, making it total 0.01 ml and this amount was injected IM in the right thigh muscle.

Within 1 minute, the hamster was drowsy but awake.

10.44 am Electro-incision x 3 warts. Large blood vessel ruptured when left thigh wart was excised with more skin. Blood flooded lower half of the hamster. Imagine a dog with half the body with blood. It was not possible to ligate the big vein supplying this wart as in the dog. Electro-incision hopefully would cut and coagulate the vessel. But it could not as it would be a big vessel. A big wart grows big and the blood vessel also grows big too to supply more blood.
10.50 am End of surgery. Wakes up. Gave isoflurane gas to stitch up.

10.54am suture 4/0 dexon
