My niece has three pit bulls – all WONDERFUL dogs. She has two neutered males and one female.
The dogs all got along fairly well initially. Her older boy had some issues with the younger one, but nothing that couldn't be handled with a stern voice {"hey!" or "Knock it off" kind of thing}. Most of their issues revolved around the spayed female, who is younger than both males and best buddy to both.
Then suddenly.. one day... The older boy went after the younger in a BIG way when he tried to lie down beside the girl. It took three adults to stop their fighting -- during which BTW, neither dog made any attempt to bite at the humans; their aggression does NOT transfer to humans, none of them have ever shown any signs of aggression or dominance or even really irritation with people -- and ever since that fight the dogs cannot be together at all.
They have to play this silly dog juggle -- one of the boys has to stay in the kitchen at all times, they cannot be outside together, they cannot be in the car together unless crated and in different seats.
It's crazy -- and they are both nuetered.
I have no problem with pits as a breed; I rather like them. But I would NEVER have two males, EVER, because I understand that male/male aggression is not uncommon with the breed, and these dogs are STRONG. They will NOT lose a fight and the real fights are very difficult to stop.
I love my nieces dogs; I enjoy being at her place with them, but I'd never have them come stay here with me, not with Keoki here. No way.
I'd think long and hard about this decision. I know you're in a tough position.
You need to hope for the best, but be prepared for the worst.
Do you have a way to keep them separate from one another if they do not get along?
