HOME: When Stryder gets all riled up, or frustrated that I'm taking too long... he will just start getting into it with Kiba. It's not regular play, he just kinda goes off on her and more than once recently he'd been doing it a bit too hard and making her yelp. DOGPARK: Yesturday we went to the dogpark... Stryder was being a bum so I found some toys in the far corner to play with. He was fine playing with me, or with Kiba. If any other dogs came by and just stood next to us watching (like right next to me.. stepping on my foot) he was fine. But any attempt to join in on the fun he'd go after them. I dont know if its just because he's overstimulated or what.. or if it has anything to do with him not being neutered. This kinda scared me yesturday at the dogpark. It's sooo not like him.. he's the soft cuddly bug that often comes and hides behind me at the dogpark when he's bitten off more than he can chew. Help? Any ideas?
