Introducing desexed male dog to a male dog?

[Parky1]

Hi, I have three dogs: 6yo male Shih Tzu (not desexed), 4yo Pomeranian (desexed female) and 1yo Lhasa Apso (desexed female).

My male Shih Tzu gets aggressive near new dogs, but is completely fine after a few days, as they were the cases when i brought the younger dogs in. (Pom had been a 2yo dog, and the Lhasa Apso a pup)

My cousin has an American Staffy, 2.5yo male. He is unable to keep the dog due to unavoidable circumstances and begged me to take his dog, as the only alternative option would be to send the Staffy to a shelter.

I decided to TRY taking him in. Staffy isn't desexed yet but surgery has been booked for tomorrow.
According to my cousin, the dog is extremely gentle and gets along with other dogs fine, but he has never lived with another male dog before.

I am still very worried about how my dogs will react to the new staffy, as he would be much bigger and possibly more aggressive than any dogs i have ever owned.

Also the dog will be brought to my house straight after the surgery D: i had initially planned on introducing the dogs on a walk or something, but since Staffy will not be able to exercise for a few days I am now completely lost as to what to do. (I have no choice but to do this as my cousin leaves the country this weekend, and I AM going on a week long trip next Wednesday so really need the new dog to have settled comfortably before i leave. My cousin had asked me at the last minute as the friend who promised to take the dog backed out)

My whole family are great dog lovers but we are still extremely worried as we never owned a dog larger than Lhasa apso...

Please Please pleaseee help!!!

Just don't do it - especially if you are already worried. It's going to take quite some time for the effects of castration to be seen in any case, and bringing him in where there is already an entire male, at a time when he's bound to be upset and bewildered, is, I think, just asking for trouble. And don't count on the new dog remotely being settled in by next Wednesday!! His surgery won't have healed by then (stitches out after 10 days) in any case.

Best I can offer is you'd have to crate this new dog, for starters. I think your cousin is taking advantage of you big time, and if only for the sake of your own establshed 'pack' this would be a step too far, for me.

ps So what if this doesn't work out - your cousin will be gone, leaving you to pick up the pieces, take the dog to the Shelter perhaps - nice one!
