Chuck is a great dog. If your 3 year old is a child, Chuck is gentle but jumps up a bit and that would overpower a 3 year old. If the 3 year old you mention is the dog, well it sounds from your other thread on Marble that they might get on very well. Chuck is very energetic and lively. I have no idea what he would be like inside, maybe the pound staff could advise. Regarding the time a dog has, a surrender has one day and a stray has 5 days. DID try and do their best to keep the dogs alive. Chuck is still there so some things are working in his favour. He has been in too long and really needs a foster asap.
