First off... Welcome to YT and Yorkies!!!
A: The person that gave me Molly said she was fixed but I don't see a scar. Is that normal?
This could be completely normal, one of mine had laser method and she has no scar. But it is also possible she was not spayed, if she had surgery, the person who gave her to you could tell you the place and docter that did the procedure
B: Molly if I don't hold her and just sit on the floor she will rub her back against me or the furniture. Again is that a yorkie thing?
Yup
C: How much and what do you guys feet your yorkies I am using Iams at the time.
Iams is not the best quality food. there are some links for better quality dog food here : http://www.yorkietalk.com/forums/yor...ing-chart.html
D: What kind of vitamins do you guys use?
We don't use vitamins, but supplement Coconut oil
E: Molly also does not drink much, at least I think she does not drink much. Again is that normal? But she does pee.
A general rule of thumb (this can vary depending on weather/activity levels, etc) is approx one ounce per lb of body weight of water a day. Hopefully you have had her checked thoroughly by your vet
Please if you can help me email me back. I just want to do the best I can for her.
Thanks Sandra M.
