But
he is now 5 months old and weighs 42 lbs
I'm not sure how long they keep growing and / or how big he will get. His mother was 70lbs and his father was around 30 lbs
thanks
I think the “breeder” - these dogs aren’t really a breed- wasn’t very knowledgeable to give you that estimate. Agree with the other poster that over 50 lbs would make sense. Sounds like a super cute dog though! And probably will have a sweet and smart personality. I have a mixed breed puppy that’s about 4 months; when I got her about a month ago she was 8.5 lbs and is up to 15 and looks a little skinny despite eating an insane amount every day. My vet said she will absolutely be bigger than I was told (I was told an adult weight of 25 lbs ...). It’s a gamble with puppies, and even if you were told the truth about the dad (did you meet the male dog, or just the mother? It’s possible the seller downplayed the size of the male to make the puppies sound more appealing) some puppies will take after one parent much more than the other so he might just be a big boy and look more like the mom.
Training is HUGE! I had dogs as a kid and my parents weren’t great about training them and those dogs ran the house. The first dog I got on my one was a stray I took in as a puppy who turned into a pit mix with the strength of a dog twice his size, or at least it felt that way. I took him to basic obedience group classes for 6 weeks and was consistent at home with what he was learning in class and he was the most gentle, well mannered dog as an adult you could dream of. He was 4-5 months when I got him- now is the time to start training.
Also if you’re not already I would crate train- the dog will like having a safe “den” , and it’s nice to have a spot for them when you have guests or workmen over while they’re still wild and puppyish.
Regarding size, ask your vets opinion, and google estimating puppy’s adult size. There are online calculators that just input the age and current weight and you’ll get an estimate. Not sure how accurate they are but for my dog it’s looking like the estimate is closer to what I’m seeing than what the rescue people told me when I adopted her.
Good luck! 5 months is a rambunctious age but sweet too. He’ll turn out to be the perfect size because you’ll be in love with him by the time he gets to adult size and won’t care what he weighs

(and I’m guessing he’ll end up 55-60 lbs)
