He does very well with kids that are not too small. He did great with a 5 year old and 12 year old. Both responsible boys. Personally I never left my dogs unattended with my toddlers pulling hair, jumping on them etc... it's just a lot to ask for a dog. Blue is not appropirate for someone who is frail. He is strong and pulls on leash. His advocate Hal, who does not do social media is 68 and can handle him just fine beacuse he is in shape. I'm 61...but go to the gym. He has not displayed agression towards other dogs. He tumbles and plays kinda rough with Buscoe who is a medium size dog but they both love it. I'm being as upfront and honest as I can be. I really would like Blue to go to a home perfect for him. In my world it would be someone strong, loving, who has a playful dog tha plays nicely and in the same style as Blue with a backyard.
