Our pup is 3 months old. He is SO VERY sweet and we love him to death. We only have one issue really...Once or twice a day when he is playing, he gets very excited and starts "attacking" everyone...by attacking I mean he jumps and bites (pretty hard) on whoever is nearby. He literally spazzes out, weve tried telling him no, ignoring him (he will just attack the backs of our legs when we do that!) giving him a chew toy to distract him, take him out to play...you get the idea! Nothing distracts him from this ballistic state! Is it okay to give him a "doggy time out"? Ive thought maybe I could put him in the bathroom or his crate for just a bit so he would calm down but I dont know if that will in some way backfire and make him afraid of his crate or wherever I put him? Any recommendations? Thank you so much for any input!
