Ok, Im getting pretty distraught over this one. Everything else is going really well with my 11 wk old pup, except play time. He's got alot of energy. Like ALOT (even after an hour long walk today). So much that I need to put him in his crate when it's time to calm down at night. I don't mind the energy so much, but his bite is really hard and he makes my hand bleed every night when I try to play with him. He's got those needle teeth, and someone told me the bite might be his possible blue heeler in him. He's not being aggressive, just trying to play (I think...). I don't know what I can do to correct this, and to teach him is bite is too hard. We're prolly gonna start puppy training next week, but I feel like I can't wait that long. I've tried holding his snout, I've tried ignoring him. If I ignore him, he just goes off and plays with something else. Doesn't get too bent out of shape. I could use anything on this one. My friend got his hand bit pretty good and I had to take him home because I didn't want him getting hurt. I read an ankle biting post about a spray bottle. could that work? Anything?
