Has she been spayed? If not spayed, she may be having symptoms of a false pregnancy and be feeling maternal. Is this behavior recent or has it been going on a long time? Sometimes dogs act crazy from boredom or anxiety. Have there been changes in the family or household that might make her anxious? I would try to distract her with a game of fetch, chase the Chihuahua, find the squeeky toy,etc.Compulsive behaviors can be difficult to stop in animals and people.
she has been doing this practically ever since I got the two puppies when they were 3-4 months old.
I wonder if she started licking the boy's ears as a way to comfort herself when she was anxious in this new environment. Now it's sort of a habit for her. If her mouth is anywhere near his ear, she has to lick it or any part of him ;) She mostly does it when they are relaxed.
It is interesting, however, that she has not been spayed. I wasn't able to get it done when the boy had the surgery at 6 months old, since she was sick for the first year of her life. Now I can't get it done since I can't leave her overnight at the vet all alone :,(
Why would she need to stay at the vet overnight ? None of my animals ever stay overnight at the vets for any reason. Mine are dropped off the morning of surgery and are brought home as soon as the anesthetic has worn off.
I've called about 10 vets in manhattan and they all said the puppy must stay overnight. The only way I would consider it is if I can take her home at night.
She is just very dependant on having someone she knows around her, either me, or if I'm at work, she follows the Chihuahua around. She gets very anxious if a stranger holds her and I walk away. I just can't imagine how anxious she would be if I left her alone overnight with strangers. It seems unimaginable to me.
When the boy was fixed it was very traumatic even though he is more independent and outgoing. The next morning when I picked him up he seemed totally out of sorts and traumatized. His eyes were blank and expressionless, like he didn't know what happened and felt abandoned. Even a year later I feel terribly guilty about it all.
