Dog Affection causing dislike in other dog

[Tielylover]

I asked this on a chihuahua forum as well, but perhaps I'd get some opinions from others who are general animal enthusiasts like me. The chihuahua forum is mostly about chichis. Anyway, I have a new chihuahua. She is small, like the other one, and female. Neither of my female chihuahuas are fixed. Mava is the older small one and she is fine with everything and everyone (except my larger male tiel, he scratched her and she dislikes him now and is terrified of him). I got a new small female chi, and she is fine with everyone except my mother! I am an adult, but my mother lives with me (long story, but it involves an abusive father/her husband and I refused to leave home without her) and she loves all of our animals (including my White's tree frog, but we can't really play with him/her, no idea of the gender).

The thing is, she wanted this new chi SO badly and she wanted the chi to love her. She is at home by herself a lot (she works, but not many hours, its more a 'boredom' thing than an 'I need to work' thing) and really loves our animals. She loves the tiels and since she's home more than me, they like her best since she gets almost non-stop time loving and playing with them. She also does the same with the dogs. She adores Snorkle, the male Shorkie in my sig. Yes, he is fixed. We would never leave an un-fixed male with two non-fixed females. The chis are too small to get fixed. The vet said it was a VERY risky procedure because of their size and they may not survive, so we just opted to not bother. The male was fixed anyway, so there was no issue with possible puppies and he also now leaves Mava alone when she is in heat.

The new chi, we named her Nestle since she is chocolate like Mava, has tried to love my mother MANY times and get close to her, but Snorkle will bite and growl at her. He does not do this to Mava. We do not understand why he's treating Nes like this. She's now terrified to go near my mother because Snorkle is keeping her occupied. He is insanely affectionate toward her now, unlike before we got Nes. He will just lay on her lap for hours without moving and growl if Nes comes near. Mava has clearance to do whatever she wants without Snork getting upset. But Nes is so scared. My mother almost cried because Nes runs away when my mother tries to pet her or pick her up because she's scared of the other dog. Nes is a puppy still, so we're going to try locking Snork out of the room and let my mom bond with Nes because she needs these dogs to love her since she's at home so much. Is there anything we can do to help Snork and Nes not...hate each other? It would be great for me and my mother if the dogs could all get along. We're used to keeping him away from the birds, but not the other DOGS! He isn't large enough to hurt her, but he scares her enough to keep her away from my mother.

Long story short, clingy shorkie biting new chihuahua whenever she gets close to my mother. Help?

Hmm. You're going to have to do some training with Snorkle. Whenever he growls, put him away from your mom and tell him "no" firmly. Whenever he's nice, have your mother give him affection. You have to be the ALPHA for him and show him it's not acceptable to bite the other dogs, especially not a puppy. My grandmothers dog is the same way - overly protective of dogs that she doesn't view as "belonging" to her human (my grandmother has 2 dogs, a dausch and a chi/poodle mix, the poodle mix bites everything but the dausch if it gets near my grandmother). Dogs get jealous. Some socializing with the puppy in neutral territory will help too, to get him used to the new dog.
