Hi when I got Pixie at 8 weeks she weighed 1.75lbs now at 17 weeks she weighs 3.75..
I feed her wellness just for puppy and I keep food in her dish at all times so that she can eat when she is hungry.
My question is.........is her growth normal or is she growing to fast and is she overweight.
Should I continue to let her free feed or just give her food 3 times a day.
I just don't want to her to have weight problems at a young age.
any suggestions?
