I am feeling like I'm failing in the borzoi parent department. I might be hard on myself.

I have a 7 month old pup. He's getting bigger and has big feelings about things he used to tolerate. I'm guessing this is the teenage phase.

We take him on walks, we play with different toys, he gets out and runs if weather permits it. He has crazy zoomies. Most of the dogs I have experience with mastiff/bully type breeds. The difference is very clear when playing. I'm used to being body slammed, grappled and nipped. My sweet big borzoi puppy loves to treat my arm like his favorite lore toy. He opens real wide while darting around and latches onto my arm. It's a tolerable pain (granted I think I have a high pain tolerance) the first time, but after continuous playful chomps and several attempts to get him to stop (trying to redirect him with toys, stopping with a firm no, turning away is difficult when your forearm is in his mouth and being boring) the bites are being tested and he bites harder for me to play back .

I don't have kids, but I live around a lot of kids that can -stupidly- run up to a dog to pet it. I don't what this to get out of hand. I know those hard crazed zoomie make it near impossible to reach him with a reset command like "all done".

I have a trainer scheduled next month, but what can I do now to help me in the future?

Has anyone else went through this? He has his adult teeth and I swear those big canines cut through my arm like butter.

Hard core zoomies chomps last less than 10 chomps with most attempts pulling/tugging at my clothes.

Any and all advice or stories welcomed

We’re having to stay in a hotel due to damage to our house from Helene. He and my other dog are already jumping between the beds, but then he does this. He’s something else lol
