I'm watching a female Jack Russell Terrier who's 12 years old for the first time. She is not used to anyone but her owner. I'm a pet sitter. I started watching her yesterday afternoon. She is very frightened and won't let me get close to her unless I give her a treat or reward but then only for a short amount of time.
Also in order for her to go outside to go to the bathroom she needs to be on a leash. She isn't used to a leash and will try to bite me if I try and put one on her. So she has been going to the bathroom on a towel as I haven't been successful in even petting her let alone getting a leash on her. She will try and bite if I try to pet her. She will take a treat out of my hand and I praise her for it. I also sternly tell her no if she tries to bite me. Any suggestions would be appreciated. I'm hoping to help Moxie (the dog) have a good experience in my care and ease Mom's concerns.
Thanks in advance
