my 2yr old bitch Allie has always got on really well with my 2 cats and my rabbit. she has always been slightly hyperactive no matter how long I walk her for. I had her spayed a couple of months back and suddenly she has became excessivly wanting of my affection and is starting to leap all over when i go to pet one of the others. she's not being vicious at all, just very jumpy and licky.
