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.
