Grain Free Food & Weight Gain My Madison is 4 years old and I have been feeding her Acana grain free for about 6 months. She absolutely loves this food but since she has been eating it she has gained 3 lbs. Does anyone think this could be from the food? Someone else said to have her thyroid checked. Does anyone have any experience with this? I don't want to take her off the food unless I have to but if it is the cause of her weight gain I will. Thanks so much for your help!! |
