3149. Dr Sing Kong Yuen shares tip on how to make the minimal skin incision in spaying a dog

Many owners feel happier if they see a short skin incision in their dog after spay. There is key-hole spay surgery but it is expensive. Knowing the location and where to incise the skin can result in a less than 2-cm skin incision using a scalpel.

Video as follows:

3148. A dwarf hamster has a heavy painful ear tumour

The dwarf hamster passed bluish grey powdery stools for many weeks. Why?
The colour looked similar to the pelleted bedding. 
"Your hamster eats the pelleted litter too," I said to an incredulous owner. Why eat bedding when the hamster has lots of food provided. She was a voracious eater. She weighed 60 g on admission but had this watery diarrhoea.

I warded her at the clinic and her bedding was paper towels. Her long lower front teeth had curved inwards up the roof of the mouth. These teeth were clipped short. Oral antibiotics given.

The next day, her stools were light brownish watery diarrhoea. By 3rd day, the stools were dark brown and better formed. Lots of stool pellets seen. Hamster active. See video.

Surgery to remove ear tumour scheduled 2 days later.

Ringworm is contagious. The dam might have had been infected during clipping. The kitten gets infected from direct contact, nursing.

Start to wean kitten now. By 5th week, weaned. Anti-fungal wash and oral medication.

The dog came in for 2 days of diarrhoea. On physical examination, there was a large left submandibular tumour, bigger than a golf ball. It is lobulated. It was not present when we removed the left lower inside cheek tumour 5 months ago.  

Only the urea and creatinine is below normal. Other values for liver and haematology are normal.

3146. INTERN A 4-week-old kitten has generalised ringworm

Sep 19, 2017

A 2-year-old cat had caesarean section 4 weeks ago. She was clipped before surgery.
Today, the owner came as the dam was shivering yesterday and had skin disease. The kitten was also having extensive skin disease.


Ringworm  is a fungal infection of the top layers of the skin and hair. The kinds of fungi that cause ringworm are called dermatophytes The most common dermatophyte in cats and dogs is called Microsporum canis.

Diagnosing Ringworm

1. Ultraviolet light to screen for ringworm. About half of M. canis cases will "glow" when exposed to its ultraviolet light.

2. Hair from the lesions, which is then examined microscopically.

3. Culture test that grows the ringworm fungus.
A sample from the lesion is placed in a special medium designed to grow ringworm. Needs 2 weeks to know the result.

4-week-old kitten has classic signs of ringworm, face and body as she suckles from the mum.
Dam's belly had ringworm. Contact.
Dam had shivering yesterday. Likely milk fever. Rectal temperature checked. 38.5 deg C, means no fever.

1. Separate kitten from mum now, to prevent milk fever stiffening of legs and muscle tremors due to insufficient blood calcium in the mum's blood.
2. Wean kitten on wet food and milk.
3. Treat ringworm for both for 24 days oral and wash.
4. Disinfect environment

Infected clippers
No ringworm seen under UVL if shampoo used

3144. 14-year-old large cross breed barks at 5 am

Sep 18, 2017

"I spent $1,200 veterinary fees in one day," the woman had his lame dog X-rayed by Vet 1 and Vet 2. "At the 2nd clinic, the vet gave some injection and a patch. Peaceful sleep for everyone."
"The dog will stop barking for around 4 days," I said. 
She nodded. "The neighbours complained to the police and the policemen visited me yesterday!"
She asked for a house-call to put the dog to sleep after 6 months of care-giving. Exhausted.
"There is the alternative of giving pain medication before sleeping," I advised. "You need to adjust the dosage to effect."

The owner came for the medication.
