18 week male cavapoo.
when we are sat on the sofa he will sometimes jump up and immediately start biting us quite hard on either the arm, leg or side. He doesn’t always do it but it doesn’t seem to me to be misdirected play biting. It
seems much more purposeful but I don’t know if it’s just because he’s tired: teething or whether he is maybe resource guarding (although we are usually sat on the sofa before him rather than sitting down next to him). No growling or snarling or barking at all. We stand up and cross pur arms. If he does it three times I then put him in his crate and he tends to go to sleep. It’s not just evenings when he does this though. It’s both sofas in both rooms which have sofas. Any suggestions for how to deal with this?
