Hi all I am new here and need some advice Please!!!
I just adopted a 4 Yr old yorkie, she weighs 5# She is so sweet and so excited!! but her old owner feed her nothing but cat food! I have tried a bunch of different dry and can foods and she won't eat them. it was 3 days without eating so I got really worried. I don't know if it was right or not but I cooked a pound of hamburger added some mashed carrots and peas and some cottage cheese, Gave her a 1/2 of a cup of it and she ate it all!! and has been for 2 feedings a day, for the last 3 days. What I need to know is
1. is this ok for her to eat?
2. should i be giving her a multivitamin? if yes what kind?
If not what do you who home cook for your Yorkies feed them.
any advice would be of great help!! because this has been the only thing I have been able to get her to eat
