Male dogs are nearly 27-32 kilos, female dogs are 21-25 kilos. And if a Rottweiler weighs more or less then it's high time to change its diets. After all, a lack or excess of weight can cause severe issues to the dog. On PetsTiger I found an article about the best dog food for rottweiler. Maybe it'll come in handy for dog owners. But what will be even a better thing is to go to the vet and get an examination. Sometimes a dog can weigh more or less because this particular specimen have predispositions for it.
