Miniature Schnauzer X, Female, 3 years, 6.3 kg for spaying by the concerned mother who was worried that the dog had not eaten today and wanted to wait till I completed the surgery. But I was not operating immediately.  "I hear that after spaying, my dog will not get cancer," somebody had told her. "Less chances of getting breast tumours and infection of the womb," I replied. Spayed dogs do get breast cancer but rarely.

Best surgical situation. Bloodless surgery as the dog was around 2 months after heat.
A nervous dog. The owner wanted the dog back at 5 pm.  

Surgical anaesthesia is the most important aspect of spaying 
Domitor 0.15ml IM was given as the dog was hyperexcited and therefore would not take direct isoflurane in a mask, without putting up a violent struggle. Waited 10 minutes (Clipping done in preparation room).

Isoflurane gas 1%, then 0.5% and reduced to 0.25% after ligation and removal of ovaries and uterine horns. Able to such low % due to tight-fitting 0.75 endotracheal tube. Advised intern that lower the isoflurane the better for the dog's health. Normally, the book recommends 2%. But in this case, pre-anaesthetic dose of Domitor was given and so the isoflurane % could be lowered. 
Still sleeping at end of spay. I did not give Antisedan. After 5 minutes, she woke up smoothly by herself. Coughed as I pulled out the endotracheal tube. No struggle. No crying and moving unlike the Maltese puppy (abscess in neck) was given solely isoflurane anaesthesia to minimise death from anaesthesia.  

Incision 2 cm from end of umbilical scar. Length of incision: 1.3 cm. Hooked out ovaries with long hook.
I used the scalpel cut off the taut ovarian ligament.  Bloodless. 
Uterine horn fat bloodless. Double ligate uterine body. 2/0 absorbable sutures used.

When the surgery field is bloodless, it is a pleasure to spay the female dog. I checked enlarged nipples for milk but none was present. This dog had false pregnancy nipples from previous episode. It was an uneventful surgery. I wanted the intern to be hands on to bandage the surgical site. The plaster pieces did not stick. "Why did you tape over the dog's nipple?" I asked as the plaster would not stick. This was her first time and she had to be hands on. Surprises happened with interns sometimes as they are new to the world of veterinary medicine. Finally, I asked my assistant Mr Saw to get the sticky tape to show her how to do it.  I phoned the delighted owner who could take her dog home at 9.30 pm, 3 hours after my surgery.
