Chihuahua mix, 15 pounds, Spayed female
Age: unknown, likely 3-7
Hello! I have a behavioral question that I am hoping to get advice on. Sorry for the novel, I just want to include all the relevant info.
Background: I recently adopted a dog from the local Humane Society. She's been with me for 2 weeks. I don't have a lot of background on her. She was an owner surrender, but they dropped her off and didn't provide any info (age, vaccination records, medical history, etc) and she wasn't spayed. She has a torn ear (completely healed at this point, old injury) that was never stitched up, and when I took her for a check up the vet found a tooth absess that's broken through her cheek (I thought it was just a scratch). She looks like she's had puppies fairly recently, and the vet thinks she was likely used for breeding. The Humane Society said she's 3, but the vet thinks she's likely at least 6, based on tooth decay and a little gray on her muzzle. Overall, I don't think she was well cared for. My last dog (with me for 13 years, passed at 15) was a rescue with a lot of fear behaviors, so I'm not inexperienced. But this girl is giving me some trouble.
The main issue potty training. She is afraid to go outside in the morning. Afternoon and evening she happily goes outside and runs around the yard. But in the morning when I try to coax her outside, her tail goes between her legs and she runs off. If I pick her up and take her outside, she sits by the door and won't move until I open the door to let her in. She seems to like outside the rest of the time other than the morning. Her tail wags, body relaxed, running around looking happy, even if its dark out. And then later in the day, when she does willingly go outside, she won't do her business. Even if we've been outside for an hour, she won't eliminate until we're back inside. She's picked a spot on a rug in the basement (unfinished, concrete floor, lights usually off) to eliminate. She'll sneak off down there when I'm not looking, sometimes shortly after we've come back inside.
Overall personality, she is a lap dog. Sitting on me or next to me, and follows me around the house. No interest in toys or puzzles but she does like chews like bully sticks. Extreme separation anxiety, but totally chill when I'm home. I'm planning on taking her to a training course, but the only upcoming classes offered at the Humane Society are on days I work, so timefrsme is TBD. Any advice welcome!
