It seems to me a tad early for the Vet to be so concerned so please, do not stress
yourself unduly! Yes...we are to be aware that overweight bullies isn't good but
your sweet Walter is just a baby still, plenty of time to take off excess and keep a
healthy weight. I will let others advise on puppy food amounts, I've only adopted
older bullies for a long time now.
Need pics of Walter from above so can see his waistline & from side view too. Bullies
are all shapes & sizes, he may just be a really big boy so it's hard to go by comparisons
of weight without looking at him.
Fall is coming (not soon enough for Texas) so easier for him to be outside in cooler temps
and be more active, that will help a lot! Others will advise on proper food amounts.
