Switching a puppy to a new food needs to be done very slowly. When I brought my baby home,I didnt change anything until she had been in our house and settled,about 2 weeks. Then I started with giving a piece here and there as a treat,then 1/4 new to 3/4 old,1/2 & 1/2 and so on. There was a week between each change. It is time consuming but it worked. |
