Tristan GSD and maybe collie mix
Tristan is almost 10 months old most likely, He is a rescue and they had to guess at his age.
I have been feeding him Purina pro plan large breed puppy food all this time. He seems healthy and is absolutely beautiful! Everyone comments on how beautiful he is.
Is Purina pro plan food a good food to feed him? His doctor says it is and his puppy trainer said yes also.
