How much should a well developed healthy Rottweiler puppy weigh? The dog has large parents and both appear to be healthy also.

How old is your puppy? Male or female? Obviously every pup will be different. Until I know the age and sex of your pup, I can give you a general idea. My 6 month old male weighs 58 lbs and my 5 month old female weighs 49 lbs. and my pups are very well taken care of. My male is just a bit on the small side as many other 6 month old males tend to be pushing 70 lbs but you get the idea. Puppies will have different growth spurts.

I just weighed my year old Lab, Holly. She weighed 50 pounds, which is just what such a small Lab should weigh. I know that is what she should weigh because I check her as explained in this link, LongLiveYourDog.com - Life Span Study - Rate Your Dog (http://www.longliveyourdog.com/twoplus/RateYourDog.aspx)

Body condition is much more important then weight. Recently I saw a litter mate to Holly and a full brother from an earlier litter. They were both good lean Labs, but were bigger than Holly and would weigh more.

If your Rott is between 4 months and a year, and still eating puppy chow, you should change him to adult chow. It slows growth and allows more time to develop sturdy joints. Keeping large breed puppies lean is important too for the same reason. It may be a little longer until they reach their full size, but they will have sturdier bones and joints.

As Katie states, hard to tell what size and weight your rottie will be when full grown. But, you can pretty much get an idea by the size & weight of the parents. Expect your dog to be somewhere in that range. As an added note, the reason labman is mentioning the food switch to adult chow is very important. Rotties are prone to ACL damage & hip dysplasia. Slowing down the rate of growth (it doesn't stop the growth, just slows it down) & keeping him trim & lean, will give your dog every advantage over these genetic issues as he ages.
