Bear with me this could be a long one...I have a 2 year old spayed staff bitch who is loved spoilt and adored. She is well looked after well trained well exercised, dog friendly people friendly and well socilaised. My other half's mum has a heinz 57 I am certain he has staff in him somewhere, a terrier of some form and i think collie plus some others. He is three (ish) up until may 2010 she lived in a house with a big garden so he ran around there until his hearts content. However she has now moved to a bungalow with no garden but she doesn't walk him....ever. As a result the poor dog is getting so depressed, he has basic training, he can sit and doesn't destroy the house he can be left and is house trained, that's where it stops, he has no recall and can't do anything else, he still mouths and jumps up at everyone, and now due to lack of exercise when he does go out he barks at everyone dogs people anything, but it is excitement. She has finally agreed to think about rehoming and a big part of me would love to take him on as i know he could be a wonderful dog (he's a bit overweight too at the min) but i think he would take to agility brilliantly (Lexi, my staff hates agility, loves flyball but will not do agility) I know he would take a lot of work and i am prepared for that. They have been walked together on extendable leads, Lexi jumps all over him and he tends to ignore her but i think thats because he is so excited about being out of the house. They have never been offlead together, infact he has never been offlead anywhere but a garden ever. He is castrated. Could this work? Could i bring this dog into our home, how do i make my dog accept him with no issues? I have a dog trainer who I'd trust with my life so I am going to ask for her help but just wanted your opinions. I'm very nervous as he is obviously very bouncy and so is Lexi and I'm worried if i don't do it properly it could end up with bouncyness becoming ott and ending in agression, or Lexi taking the huff and not liking himbeing in her house. When out walking him she isn't bothered if you fuss him as long as she gets a fuss too. Any advice?
