Dog problemss..Need more answers.?

Question

I have a very skinny (60 pounds maby) white boxer. Ive been feeding him and my other 2 dogs (another Boxer and a Brazilian Mastiff) costco food...Atta Boy. I work at a dog groomers, we supply Solid Gold food, ive taken sample bags and he likes it, although its expensive but would be willing to buy it if its a very good choice of food. My question is what would you give your dog to gain weight? Im thinking a good 15 pounds on him.

Everything in Solid Gold is pure, ive gone over the back a few times. He is my only dog semi underweight,
Other boxer (75 pounds)
Mastiff (170 pounds)
I think he just runs it all off.

Answer 1

First have him examined by a vet to make sure there are no underlying medical issues



Feed him a performance food, its for dogs that are high energy



I am sure he does not need to gain 15 pounds

Answer 2

Actually your 60 pound dog is about the right weight.For a male boxer he should weigh between 60-70 pounds.A female boxer should weigh 55-65.

I don't think any of your dogs need more food.Feed whatever amount you're already feeding them.Solid Gold is a good food

Answer 3

you should feed the separately and on a schedule once in morning and once at night. after a couple days of that they will be used to it and will eat everything in the bowl. they wont leave any left for fear of the other dog getting to "his" food bowl. over time you can control his weight by how much or little food you put into his bowl at each meal time

Answer 4

Aside from feeding him treats (start teaching him tricks), I am not sure, but I would call your vet and ask them. They would have the best answer.
