My vet suggested I put my 10 year old Yorkie on Senior Food. He needs to lose weight and has become more ative since we have a 16 month old chasing and playing with him. I need a food that has small kibble becasue he does not like to chew. He refused to eat the nutromax senior he left it and would go eat Brandis Royal Canin. Will senior food hurt Brandi if she was to eat at 16 month. Thank you for any information that canb be provided.
