Leonberger Q&A

I would like to know the average weight for a 5 month old Leo puppy. My puppy was sick with parvo and spent a week at the vet's. He got through it very well. I am wondering, though, if he is underweight for his age. He seems fine (I can feel his ribs but not too much) and layful again, so I am happy no matter what, but I would like to know if he is within standards for the breed at that age.

My leonberger was around 30kg at 5 months. I wouldn't worry too much about what the scales say, it's better to go by how he looks and behaves. If you can feel his ribs with gentle pressure he's about right. It's also difficult to consult charts with leonbergers as these dogs are easy to just feed and feed and many people's leos weigh enormous amounts. Its not good for them to put on too much weight as it affects their bone development.

At the following website, you will find the averages for Leos on their weights. Note these weights are at the END of the month not the beginning. Although some Leos are lighter or heavier than these weights. http://www.leonbergerdogs.co.uk/ARCANINE_Leonbergers/growth.html I am not associated with this breeder just appreciate the growth chart. I have a similar situation with my Leo who has a genetic disorder of the pancreas. His weight is off and may never catch up.

We now have our third giant breed puppy. We had a Newfoundland and a Leonberger over the years. The rule of thumb that seemed to work for us is the dog weighed about 10 lbs. for each month, 5 months old / 50 lbs, 6 months old / 60 lbs, etc. We found that this seems to be a pretty good scale for a male who is in good shape. At these weights our dogs remained slightly on the thin side, a good thing for a fast growing puppy. Much less pressure on growing bones and joints.

My leo pup weighed 78lbs at 5 months he was not to fat and not to thin. but i like what other person said it is more important that your pup is healthy and happy.

We've owned 3 giants over the years, one Newfoundland and Two Leonbergers. Our experience has been each weighed approx. 10 lbs. per month. A lot of this has to do with the parents adult size. Our current male Leonberger is 11 months old and weighs 125lbs his dad is 2 1/2 years old and weighs in at 170 lbs. Just be sure that your dog does not become over weight, this is far worse for your dog. These giants take much longer time to mature and reach their full potential. Sometimes it is hard to realize that a year old, 100 +++ pound dog is really only a puppy Just enjoy the time you have with your dog as a puppy and let him grow at a nice slow pace..
