Hi Dr Sing

(I can't seem to find the email for Dr Sing, could you put this email through to him, thank you very much, :) )

This email is regarding the neuter of my 3year old jack Russell terrier some time late May, XXX. After 3 weeks the blood clot has subsided. Till now all is well and his is also less aggressive and more good natured now. However.. every time I return home, XXX would greet me enthusiastically as usual. But after a while, he would stop to lick his genitals. I have noticed that there seems to be another set of testicles, which seems to have emerged from nowhere. It would appear at the middle along the penis. Is this normal? Everything else has been normal and his wound is completely healed.

I look forward to your reply. Thank you!

Thank you for the feedback.

It is hard to diagnose by e-mails. As the dog is very fierce, it is hard for him to come to the surgery to be examined properly.  Do you mean there are two swellings?

From your description, the area is probably below the os penis (penile bone). If the male dog licks that area, it is possible that he has had some small urinary stones stuck behind the os penis. The stones get stuck partially and so he can urinate without problem. But these stones irritate that narrowed urethra behind the os penis.

If he can pee normally, there is no problem for the time being. However, he may pee abnormally sometimes. Do observe him well. Here are my recommendations:

1. Use a sterile syringe, collect the urine for analysis.
2. Come to the Surgery to get a urine collection bottle to put the urine in.
3. The urine will be sent to the Lab for analysis for urinary stones and bacteria.
3. E-mail me a picture of the area involved (front view & side view).

Restraining an aggressive Jack Russell for neuter

 
He curled his upper lips up and bared his fangs if any outsider wanted to touch him. I had encountered such aggressive Jack Russells. Usually males.

What to do in such a case?

When the owner brings him in for neuter, ask the owner to restrain him for tranquilisation. In this case, I injected 0.2 ml of xylazine 2% tranquiliser IM as the owner arm-locked the dog.

I put the dog into the crate. Normal ones would feel sleepy. This dog was fully alert and baring his fangs 30 minutes later.

"What should you do?" I asked my new vet assistant who has to learn on the job. He took out a dog muzzle. His usual way was to put his hand beside the dog's chest and slowly touch the dog, moving the muzzle up.

The Jack Russell eyed his hand movement and snapped in anticipation of being handled by a stranger.

"The muzzle is of no use," I said. "What to do if you don't want to be bitten?"

The assistant was silent. He had to get the dog out of the crate to the surgery room for neuter. The dog was a bright as daylight waiting to pounce onto his hand.

What to do?
There are 2 ways. Use a thick towel and cover his head. Use a lasso over his neck and get him out.

He had never seen a lasso before and we used this method. The dog was not as strong as before. Gas mask using 8% gas anaesthesia knocked him down. An endotracheal tube was put into his lungs to bring the anaesthesia to keep him pain free. Surprising 1% anaesthesia instead of the usual 2% kept him pain-free for neutering. He was put in the crate after his skin wound was plastered.

No dogs would be allowed to go home till around 4 hours after surgery. Preferably overnight but most Singapore owners want their dog home in the evening or earlier.

In this case, the owner said he had an Elizabeth collar but he did not bring it with him. So he needed not purchase one from the Surgery and increased his veterinary cost of neutering.

30 minutes later, my assistant said: "The dog is bleeding a lot!" The dog's muzzle was stained bright red. The newspapers were stained bright red too. The Jack Russell's eyes stared directly at me, pupils dilated, fangs exposed, ready to attack.

 

What to do?
I did not expect the dog to lick vigorously his surgical wound. Blood flowed and seeped into his scrotum. It looked as if he was not neutered as his scrotum swelled to the full. It seemed to be a "con" job from an outsider's point of view as the scrotal bags should be deflated with the removal of two testes.


How to handle this bleeding episode?

In this case, the dog's adrenaline level was at all-time high. He should not be given any tranquiliser or painkiller injection in case his heart fails and he dies attributed to adverse drug injections.

"As long as you stand in front of him," I said to the vet assistant. "He will not lick his wound. He has to look at you and anticipate when you are going to nap him." So the assistant stood around him for a full hour while I asked the owner to come down.

"I can't come down now," the owner said. He was working.

"You need to come down," I said. "Your dog is bleeding and he is too aggressive. When you come, he quietens down."

The owner and his daughter came with the e-collar. They did not comment but the bleeding was a lot and the swelling of the neuter site and the scrotum was as big as it could be. A few bright red drops of blood trickled out of the stitched area.

"This 12.5-sized collar will not stop the dog from licking," I said. The owner put in the 15.0-sized collar from the Surgery.

What to do now?


So the dog be put under anaesthesia and the wound opened up to drain the blood out? This was one option.

Now, the vet has to be aware that any anaesthesia or tranquiliser in this highly strung dog may or may not kill him as he had anaesthesia recently. A dead dog is never appreciated by the owner no matter how clever the vet surgeon is.

I had to choose the safer option of maintaining the status quo. Not doing anything.

"Take the dog home and put him in a cage. No running around the house." I advised the owner. "Tel me if the swelling gets bigger or there is more bleeding. The bleeding is due to the dog licking the wound vigorously and not due to the bleeding from the neuter." I showed the owner the extensive bluish black skin discoloration of the whole penile area bruised by the dog's tongue.

Could the dog's licking cause the sutures to loosen and cause bleeding from the spermatic artery and veins?

In my experience, this was not the case. In any case, I had ligated the stump twice and ensured the stump had gone back into the inguinal canal and probably into the abdomen. I ligated quite near the testes so as to minimise trauma by not stretching out the cord and separating the spermatic blood vessels from the cremaster muscle as I used to do. This is the open method. There are two methods of neutering and I use the closed method ligating the whole sheath with the spermatic blood vessels and the cremaster muscle inside nowadays. If the first ligation broke down during licking, there would be a second one.

Experience gained
An appropriate-sized e-collar should be given to any dog after neutering or spaying. This is our usual practice although large breeds are seldom given e-collars. In this case, the owner said he had one. Although he did not bring it, we did not expect the dog to be so vigorous in his licking of the skin wound as he had a xylazine tranquiliser.

Oh what a wound! You should have lent them an e collar, straight away after surgery . but anyway. maybe it's a good lesson learnt

INFO FOR JACK RUSSELL OWNERS:

Many male Jack Russell puppies in Singapore, more than other small breeds, show their teeth and aggression at around 3 months of age towards family members especially females.

In one case, the young lady owner in her twenties was trying to be firm to train the 3-month-old Jack Russell puppy.

The mother and aunties "sabotage" her by being gentle towards this young pup and let him have his way. "Such a young puppy. Why be so fierce to him?"

"How does the puppy react to the father?" I asked the porcelain-fair sweetheart-shaped face whose thick and jet black eye brows just force a person's eyes to look at her when talking to her. 

The young lady laughed: "The father is usually not at home. He travels overseas. However, when he comes home, he likes to play "tug of war" with this puppy by pulling things from his mouth. Both enjoy this game."

"Tugs of war just promotes the aggressiveness of the puppy," I said seriously. "The puppy now wants to be the leader of the pack by testing the pack members. That means 3 of you ladies!

"He bites to show that he is the boss. Usually this happens in a Singapore family with many female members as they are nurturing of the puppy and don't expect such behaviour which is normal in the dog pack order."

In the above case of XXX, the male Jack Russell has  matured and is difficult to control. He bites any outsider who approaches him, including family friends and relatives.

Neutering is the practical option to reduce his male sex hormones which are the drivers of aggressive behaviour. But this is best done at around 6 months of age and not till some years later.  

Animal cruelty and death under anaesthesia are two main issues worrying the dog owner. A very small percentage will die under general anaesthesia due but >99% of the dogs do not.

Without neutering, aggression and biting of some family members and friends continue to old age. Urine marking makes the house or apartment smelly.

There are a few aggressive female Jack Russells too but they are alpha females.
