Hi!
We went to the doctor with our Biewer, she did conclude alergi. So it is very important to pay close attention to what you give to the dog.
Hill has a product that is very good for dogs that have alergi. Otherwise, it is to try out foods and snacks.
All dogs have different and reacts differently. It is wise to give one thing at a time. So you then know for sure what they can eat and what they can not eat.
When switching food to the dog, then you should give this for 2 months before you know for sure if they can tolerate it or not. So do not stop after a day or 2.
Have a nice day!
