I've just met up with the usual crowd of dogs with Jake my 8 month old Border Collie. He's known by all for his loving and calm behaviour around the dogs/bitches and their owners. So you can imagine my horror when I heard barking and growling, really aggressive barking and saw it was Jake who was chasing after another dog. As someone said, there was utter hatred on his face. The problem is he is big for his age, 56lbs and I dread to think what he would have done to this smaller dog.
I reprimanded him (and I mean reprimanded him!!) and obviously put him on his lead. I gave it 5 minutes and walked over to this owner to apologise. I had Jake under full control but he would have gone for this dog again, no doubt, so we moved away.
The other owners were stunned but said I should not worry, it would be a personality clash. Indeed Jake sat and all the other dogs/bitches came up to him whilst on his lead and he never batted an eyelid. But it has left me very shaken.
Am I making too much of this one off? There are two dogs who hate Jake and go for him and their owners don't seem half as worried as I was today but I take the responsiblity to other dogs and their owners seriously and I really do feel he would have not stopped at a nip.

I know you probably don't have any answers but even reassurance would do right now. I am just about to ring my vet too, he has said he won't neuter Jake until 9 months but I wondered if he might reconsider.

Thanks for listening.

Call a different vet if you want him neutered now. Vets get to make this call on their own and its not always based on what's been proven "best" for the dog but rather what they're comfortable with surgical-wise.

I would find another vet. While it's a "to each their own" sort of call, I've never heard of a vet that wanted to wait that long. IMO, that's really late, as IME, it's best to spay or neuter before those hormones kick in and they develop "mature" behaviors or habits. (i.e. same sex aggression, marking, etc.)

but neutering won't necessarily solve the problem of individualistic dog-dog hatred (where a dog is not generally dog-aggressive, but develops a hatred for a particular dog).
There's no solution but to always watch your dog and make sure you can control him.

No, of course it won't. I'm sorry if it read that way.

Of course, I did have a "hatred" issue type thing that was settled by altering the older and dominant ***, but that's completely anecdotal.

Yes but still better to go ahead and neuter him, IMO.

Thanks - I agree it could be dog-dog hatred, he's been out twice since and was still fine with other dogs/bitches on or off the lead. He saw the vet last night and is booked in for neutering on Wednesday. I was always going to have him done anyway, this is not a knee jerk reaction. I won't miss him trying to hump me 3 or 4 times a week either Emotion: smile
The vet did not seem unduly concerned by the behaviour in as much as, he intimated it was probably a one off with that particular dog. I'm cautious anyway so I'll be watching him.
Thanks again

Dear Lynda,I too own a pup that is known for excellent socialisation skills, and I know how shaken I would be if she suddenly upped another dog for the rent, because it would be VERY out of character for her. In Australia almost all vets recommend spaying at 6 months. Some (pound puppies) are spayed before 8 weeks, so that they can go to their new home with the guarantee that they will not reproduce. Whilst I admit that it takes very experienced vets to operate that young and have a high success rate, it is not more difficult to spay a dog at six months than it is at nine, especially males.

Waiting until the testicles drop and enlarge is often too late to stem aggressive behaviour. Whilst I doubt that Jakes 'turn' was due to hormonal aggression, it is not wise to wait until maturity to spay/neuter any dog, as the hormones produced by the sex organs can lead to mammary cancer in females, and marking behaviour in males. See another vet, or tell your vet politely that you do not wish to wait that long, and will go elsewhere if you have to.
See what happens.
As a customer, you have the right to decide what you think is best for your dog.
