1430. A 7-year-old Shih Tzu has a large wrist lump

Hari Raya Puasa on Jul 28, 2014. Around 10 cases seen as most vet clinics are closed.
Interesting one of a Shih Tzu, Male, 7 years coming in with a large wrist lump. "About one week," the owner said.
"If it is one week and growing so large at 8 cm x 6 cm x 6 cm," I replied. "It is not good news as cancerous cells grow very fast. I need X-rays to check whether the bones are infiltrated or involved."

X-rays show normal bones. So it was good news.
"Surgical excision may result in the dog being lame on the right fore limb," I warned. "Unless the lump is one solid ball sized and dissected out using electro-excision & cautery carefully."

Owner opted for anti-inflam injection into the lump and wait for 2 weeks.

1429. Yesin Vet Students Talk - Aug 11, 2014. Blood in the stools - check for parvovirus

As many Singapore dog owners do not vaccinate their older dogs, it is best practice to check for parvovirus when a dog passes blood in the stools. I have such adult dogs who have been to boarding purging with blood in the stools. They were positive for parvovirus.

It may be deemed negligent of the vet to overlook the test for parvovirus which is a fatal disease. Inform the owner about the test and if the owner does not want it, the vet should record this in his case notes. Should the dog be diagnosed with parvovirus by another vet when the dog continues passing bloody stools, the owner and his family may complain that the first vet was incompetent. Keeping good medical records on such advices protects the first vet against claims for compensation.

1424. Images of BKTP videos. An 8-year-old Shih Tzu has a bigger bluish breast lump

July 25, 2014

Groomer Clara popped in with a 8-year-old Shih Tzu. "She will bite if you pull her out of the crate," she warned me. "Other dogs don't do it."

So we weighed the dog + crate = 8.1 kg. She poured the dog out and the crate weighed 2.1 kg. Once out, the dog did not bite but she would hum a few soothing words and rub her shoulder when the dog got injections. Dog bites are groomer's risk.

"6 kg and normal temperature of 38.6C" I checked the vagina for discharge. There was none.
"When was the last heat bleeding?" I asked. Clara phoned the owner who said it was 4 months ago.
