how to make dogs more bulkier

Give them Fats like canola oil flax, fish, wheat germ,vegtable etc....

 

You could put her on hormones thats what my vet did my dog was very thin. So he prescribed some hormone shots{steroids}.

 

are you actually suggesting that this 15yo give his dog(a female dog) steriods?

 

This is very much what I have in mind too. Gamedog by nature have small fat reserved compared to bulkier bully show dogs. Their lean and mean physique comes with a purpose that's why they are bred this way. If your purpose in keeping this dog is to see her in action in the the ring, I don't think you have to worry much and just keep up your routines in keeping her conditioned. However, if for breeding purposes only and retire her from all these things then putting her in the kennel will do her best.
Putting her in heavy chains, mills and heavy exercises is short of saying putting her in schooling, she won't take much fat coz it will be burned as source of energy. High carbo or glucose is also the first source of that much needed energy in heavy activities ( thats why athletes are being put in this diet while in training). Workouts burns much fat and our canine friend needs twice to thrice the needed protiens for the muscles to built up or else even the glycogen contents of these muscles will later be consumed too as energy.
Vitamins, protien rich drinks/supplements, good dry dog food can only do much if the dog is in the same activities day in and day out. . . .

I just wanted to say thanks to BBK for pointing this out. This was something I was previously unaware of.

 

I certainly wouldn't put a dog on a steroid cycle just because it was too thin. While the use of synthetic hormones is definitely not without benefit, to "bulk up" a thin dog is not enough of a justification for the administration of such, IMO.
