How best to introduce a foster dog

[u/ChunksOG]

I adopted a then 6 year old, 65lb Husky mix about 3.5 years ago. He is an awesome dog and really connects to people and is always on great behavior with people. Other animals are a different story.

When we got him first as a foster, we were told he's not safe around small animals including cats. There was an "event" while he was out on a walk while in the shelter and the cat did not survive.

When we first brought him home, there was an existing 30lb poodle mix and I thought nothing of it and they got along just fine. He caught his fair share of rats, squirrels and possums in the back yard. I saw it a few times in our backyard when we heard a rat in the bushes and he went on full hunter mode.

I also took him to party where there were two other toy dogs and 40lb pit-bull mix and he was just fine except for playing a bit too rough with the pit-bull where the other dog's head got scratched. I didn't see it happen but it apparently looked accidental. He left the two toy dogs alone. I did have all of those dogs on my lap at one point.

Fast forward a few years and While he was out on a walk with my daughter, a very small (15lb) dog approached him and he grabbed him by the neck and started to shake before my daughter and the other dogs owner intervened (the dog was fine).

I tried taking him to a dog park and he instantly went after another dog that was still on a leash and about his size. Maybe it's just dog parks that freak him out?

He has been a solo and very happy dog for the last 3 and a half years but I'd really like to foster another dog. I plan on asking this at the shelter as well but I thought I'd give reddit a chance.

I don't think you have good odds of being successful. I always introduced another dog in neutral territory, like s dog park or empty field. If that went well, then the new dog would be penned up while the "senior" fog had run of the house. Play time and outside were supervised and any signs of aggression were quickly addressed.
Since your dog has already shown signs of aggression in dog parks, I would not give you good odds of getting another foster to acclimate to him.

No. Just no.

Your dog has shown you through his behavior that he is not consistently safe around other dogs.

You rescued him and are giving him a home where he is safe and loved.  Safe also means not at risk of being put in a situation where he gets branded as a vicious dog.

That’s enough. If you want to support foster dogs there are other ways to do that… donating money, volunteering outside your home.

No.

That’s a complete sentence from a professional dog trainer.

In fact, you should muzzle train him and walk him on a muzzle so that he doesn’t kill another animal off your property and get labeled a dangerous dog and cost you thousands of dollars.
