Hello. I'm a little confused about which food to feed my baby. I currently have her on Solid Gold Just a Wee Bit made with bison and she started off eating it well. This food has her doing healthy, solid waste and since she started teething I moistening her kibble to soften it. For the past few days now her appetite has lessen. Should I change her food or give it some time? I get very concerned when she doesn't have a healthy appetite. She only weighs 2.6 lbs at her last vet visit. Help!!
