DPuppy is 10.5 weeks old. We've had her since she was 8 weeks. She's a rough collie cross.
She has got to the bitey, tugging at clothes, jumping up and hanging on by her teeth phase very, very quickly. Our previous dog (also a rough collie) wasn't at this stage for a few months yet.
Oddly though she's only doing it to me. She has spent more time with me than any other member of the family and follows me around everywhere but literally as soon as I get up she will jump up and bite the backs of my knees and tug and rip at my clothing.
Is there a reason why she's doing this to me and nobody else? It's annoying and it hurts!
