I have nerver before owned a toy/small dog. I am 20 years old and am doing my best to raise "Martini" to be the best she can be! I give her Nutri-Cal everday like my vet said to, and brush her on a regular basis also. At 10 weeks old she weighs 3.1 lbs, is that too much? Also I'm not sure exactly how much to feed her? She gets to play and run outside atleast 2x a day. I think she is very smart, at 9 weeks old she knew sit and down(laydown)on command and houstraining hasn't been too hard with her either (after a few different methods). As a new owner are there any suggestions that I can do that will be better for my little one??
