I am in contact with a local trainer, but I'm just looking for more advice.
We purchased a 9 week old Rat Terrier, female, 9 days ago. She was in a fish store. Probably not the smartest option, but our first dog a 7 year old fixed male shih tzu came from a fish store & has been an amazing dog to our family.
In an effort to keep this short. Puppy did great at home all week. Normal puppy behavior. We redirected with a toy or bone. No "aggression" at all. Saturday we were at my parents house - a 3 hour drive from our house. She did great in the car. She did great most of the day. Napped very little, lots of excitement. Saturday night someone dropped a paper towel, she got it & I went to get it from her, she growled, snarled & bit/scraped my finger. I yelped & set her down. When I went to pick her up again she growled again. I waited a few minutes, & removed her from the commotion & she fell right asleep. I picked her back up & she snuggled up & slept on me like she normally does. Came home Saturday night, no problems.
Hand fed her breakfast yesterday morning, swiped my fingers through her mouth, played toys. No issues. She took a small nap in the morning, but nothing very long. Around noon she got a piece of string, my daughter (12) picked her up, got the string & puppy growled at daughter. My daughter put her right down, we put puppy in her crate & she went right to sleep. Yesterday afternoon I went to put her leash on her to take her outside, same thing, growled & snarled at me. In her crate & she went right to sleep. She was fine the rest of the night.
This morning I got her up, hand fed her, swiped through her mouth, let her play. She isn't normally allowed in my bedroom - but to sleep - but I was running late & let her in. She got a shoe. Went to take the shoe from her & she growled at me. Put her in her bed & she slept from 7:30 to about 12:30. Now she is up playing, then sleeping, up playing, then sleeping.
She puppy plays with our dog, no aggression (he mostly avoids her). She pretty much avoided my parents dog, no aggression. She does not protect her toys or her food, her crate, or her beds/blankets. She is only allowed on the couch if one of us are holding her. She understands that when she wants to get fed she has to sit nice & she will. She sleeps in a crate with a 4/430 am potty break.
It seems to me when she gets overtired/overstimulated this is happening. However, she can't seem to calm down to go to sleep if people are around. Am i interpreting this right? In any case any advice you have would be great, like I said, I have been in touch with a local trainer for private in-home lessons. Our Shih-Tzu is my "son's dog" my daughter wanted her "own dog" & hence we have a cute little 2.5 Rat Terrier that I very much want to be a welcome addition to our home.
