u/squambish

Our new dog loves my son, we got him at 8 weeks and he is now 13 weeks. He cries when my 8 year old son leaves for school and often lays as close to him as possible.

He shows no resource guarding in any aspect and was praised by the vet for how he shows no aggression with food, his paws or looking in his mouth.

The last week however, when I cuddle my son at night to go to sleep, our dog cries and bites me. If I hug my son, he jumps up and bites my arms and whines.

If my son sits on my lap, he cries jumps up, paws at me and bites me.

I have trained many animals and have dealt with resource guarding but never guarding a human.

Any advice on how to break this without ruining the protective aspect he has for my son?
