I have a 13 week old Puggle and when we first got him my 2 boys ages 6 and 8 would play with him alot(tug a war,chase,fetch, ets.) I only let them play fetch with him now! I think its too late because now he thinks my 6 year old is a big play toy. The poor kid cant go near the Cooper without Cooper jumping on him and biting him! He only seems to really target My 6 year old. How can I get him to stop? Iv tried pushing him down, I put him in his crate but the dog cant live in there when Shawn is home from school. I have even put Cooper on a leash and everytime he attempted to jump on him i stopped it.Any other suggestions would be greatly appriciated its getting to the point where my son will not come out of his bedroom!
