how big would a mastiff/pitbull mix be?
I am considering purchasing a puppy soon, and I would like to know how big a Mastiff/Pitbull mix typically grows. The father is a Mastiff, and the mother is a Pitbull. Can anyone provide insights on which parent the puppy is likely to resemble more in terms of size and appearance? Any information would be greatly appreciated. Thank you!

It would be hard to tell how they would look. However I am sure that they would be cute as can be…what puppy isn’t cute? The one thing that I would say is to check the health of the dad (mastiff) this breed has allot of heath issues with its hips and elbows and this is genetic. So ask allot of questions and even ask to call the vet of the father to talk to them. This is going to be a big dog with allot of power so training is a must. No one wants a 100+ dog running into them and knocking them down.
Again the heath issues should be looked at. Its something that cost allot of money to fix. If its even able to be fixed. This is also not going to work as an outside dog seeming as they do not get much of a winter coat on them..
good luck and let me know how it goes.

Mastiffs are pretty mellow, and pitbulls can be a crapshoot–if the parents and grandparents were well socialized, chances are the mom is well-socialized. We have a mastiff-rottweiler mix. He’s really dog aggressive and has a hard time getting to know people, and he will bite. We have to take these things into account when people come over. He’s a really great dog.
Ultimately, a mastiff/pitbull mix sounds like an ideal dog. I doubt you’d have the aggression problems we’ve had. Make sure to get him/her fixed early on to avoid aggression problems later, and socialize him or her with both people and dogs as much as possible.
Look at the size of the parents. French mastiffs can get to be in the 250 lb. + range. Pitbulls are usually around 80 lbs. So you could conceivably be looking at a 200 lb. dog. Ours is 103. Chances are that that’s about where yours would be. Any questions, send me a message.
Please don’t waste your money on such a backyard-bred mix. I *promise* you, shelters are absolutely full of pit mixes. If you want one, just adopt! Save a life instead of supporting a moron who would intentionally sell *more* mutts while dogs of the same (and better) quality are being euthanized daily.
Anyhoo, mixes are unpredictable. Well-bred purebred dogs have to follow strict breed standards, but obviously there are no standards for mixes, so there’s no real way to guess how they’ll turn out. Who knows which parent a puppy would take after? Offspring could potentially be as small as the smallest pit or as big as the biggest mastiff. Here are the average heights and weights for the two breeds (assuming you meant a Mastiff and an American Pit Bull Terrier):
FEMALE MASTIFF: 150 pounds and up. 27 inches and up.
FEMALE APBT: 30-50 pounds. 18-22 inches.
MALE MASTIFF: 160 pounds and up. 30 inches and up.
MALE APBT: 35-60 pounds. 18-22 inches.
See? Huge difference! The dad could weigh 210 pounds and the mom could weigh 30 pounds! (If the pups aren’t born yet, by the way, send that poor pit a prayer that her owner will be intelligent enough to have them delivered via c-section.)
Simple, you cant tell. When you start mixing breeds there is no way of telling what the pups will look like. I would imagine they would be big but if they take more of the pit side they will obviously be smaller. You know these pups may have health issues due to probably neither parent being health screened. Temperment is going to be hit or miss too as this breeding was obviously not done to improve that
pits can have big heads and mastiffs heads are massive too so there will probably be a c-secion happening as mm probably wont be able to deliverer naturally. Hope you or whoever is breeding them have up to £1000’s to spend on this cos thats how much it could cost
I would be very suspicious of why someone would put these two dogs together.
It isn’t someone who genuinly loves pitbulls and their gentle side, and it isn’t someone who has the future of mastiff’s at heart either.
I would say it is someone trying to build a bigger type of pitbull for dubious reasons.
For that reason I wouldn’t touch this dog with a bargepole and give the owner the satisfaction of selling his puppies easily.
It is people like that that end up giving all our lovely big breeds a bad name and possible bans.
Annie — my friend has rottie/mastiff crosses and competes them nationally in flyball. They have a great time and are most definitely not dog aggressive as they have been so well socialised.
My son just got a Pitbull/Mastiff mix. He’s still a puppy and weighs 100 lbs. He looks like a Rottweiler on steroids. He’s a really sweet and gentle dog but he will play rough if you start it. Even as a pup he’s an excellent guard dog.
There are a few real keys to dog training, whether you are trying to train your dog to come when called, sit, stop barking or any other behavior. Understanding their importance is critical to achieving rapid results that are long lasting and help develop the bond between you and your dog. Read more here https://biturl.im/aUEkI
The first is simple; you must win your dogs mind. If you don’t achieve this first then you will be struggling the all the way. When I talk about winning your dogs mind what I really mean is that your dog looks to you for all the decisions. Before you do anything else watch one of the amazing video sites that show you the 5 Golden rules to establishing yourself as the pack leader. If you aren’t putting these in place then you are setting yourself up to fail. Just at the crucial point where you really want your dog to listen they will go and do their own thing. For sure your dog may play ball occasionally or even most of the time, you may even have a dog that is obedient 99% of the time, however if you want a dog who always listens to you and does as you ask then you need to win your dogs mind.
The second key to success is to motivate your dog. It is really important that you discover what it is that your dog enjoys both in terms of exercise and play but also in terms of a reward. If you can make the experience enjoyable then you will both achieve more and look forward to training.
Some dogs love to fetch, others love agility, and other dogs simply love obedience training, or swimming out into water and retrieve. At least to start with find out what your dogs love is and help them develop this, what I am saying is work with your dog. The other point to recognize is to make training enjoyable reward your dog.
