Hi everyone

I am new to the site and wanted to introduce myself. I adopted a 8 yr old yorkie (first told she was a silky, but Dr. confirmed yesterday that she is a yorkie) on Tuesday and I am so excied about it. Well, when I adopted her, they told me she is 4 years old, but yesterday I took her to the vet for a check up and the vet says she is much older, more like 8. I don't mind, because being her age, no one would adopt her and she would most likely get killed at the county shelter. I went to the shelter after seeing her sad eyes on the website. She wasn't ready for adoption because she was not spayed. Keep in mind, she was just abandoned at the shelter the day before.
I took this poor baby home and since I can't groom her yet, I used the waterless shampoo and slicker brush to get out some dangles. She has matted hair all over her rear end. I can't get those out, but I brushed the rest of her and wiped the dirt out of her face and eyes...she looked soooo happy to have that done. I took her to the park for a walk and she just ran...I got a good workout! lol.
The vet told me that it seemed she had tumors too because she has 3 incisions on her underside...one close to her upper breast. He said this is common if they are not spayed earlier.
So...I need help with feeding her. She won't eat dryfood or treats. She picks at some wet food. I have a cat, so Coco was eating cat food! I quickly stopped that. Can anyone suggest what I can do, because at this point, she is probably soo use to what she was being fed before.
I have been brushing the areas I can brush until around Sunday or Monday when I will have her groomed. She seems to really enjoy that. She took over my cat's bed, but that's ok, becuz she never used it anyhow. Now she is running all over and looks even happier
