I took my 20 week old puppy to a puppy socialisation group today. They've been lovely and stress free in the past, just her bounding about in her element playing chase with other dogs, but today she would not stop mouthing the other puppies, culminating in her near constantly putting her mouth around the other puppies legs as she realised it was the best place to grip. They all seemed to be having a great time as when I put her on the lead the others still wanted to play, and there was no yelping (and she wasn't growling). It looked very bitey though and made me paranoid that she seemed aggressive (I don't think she is aggressive, I feel as certain as I can be that it was playing as she was waggy and enthusiastic, but perhaps I'm wrong) . Would you say this is normal behaviour, or normal playing? She's half lurcher and a lurcher owner told me they play with their mouths and run at each other with mouths wide open ('bitey face') so is it maybe a breed thing? She doesn't do this with us but mostly because we divert her biting (which isn't often, but happens when playing) with toys. Any tips on discouraging it?? I don't think I can go back to the group if it carries on 😬
