Hello, We are very close to adopting a Jack Russell, Ted (2 yo). My son and I met him today and introduced him to our dog Bella (4 yo mini golden doodle) in a park. I've always thought the best dogs I've met are JRs, but the worst dogs I've met are Jr's too! Ted seems a bit undisciplined, but calm (energetic, but not nervy), accepting of our dog and happy. The two dogs got on fine - mostly ignoring each other, polite sniffs, ran about about together a bit. The jack is ball oriented, but didn't mind when our Bella got the ball. We then took them into Ted's house and he wasn't possessive of his toys, water or food. Ted seems to be a lovely dog and is apparently also good with cats (we have two) and lives happily with a five year old human. The owners want surprisingly little (£100). But they say they don't really want to sell, but put a price on to discourage time wasters. They say they used to rent a house that they put a dog flap in, but they had to move and the new landlord doesn't want then to have pets. So, my point of posting is, what am I missing? All seems too good to be true. We had a difficult time with our first dog that we unwittingly got from a puppy farm. She had a cough, diarrhea, fleas . Although the two owners said slightly different reasons for passing the dog on, I'm not saying these peeps are nefarious, but I'm probably too trusting! What final checks or questions should I have before taking this dog on?
