I'm curious about his behaviour, he's reported to be very attached to the woman not the guy. Being a chihuahua mix (+terrier?) probably doesn't help.

It's not a nasty dog, it's a very anxious dog. It is displaying what is known as either whale-eye or half-moon eye. It does not like that level of human contact, they are putting it in a highly stressful situation.

Apparently he clings to the woman, then 'bites' her, very ambivalent. IIRC he was from a shelter.
