I Have A Bull Mastiff/Boxer Mix. He Is Two, How Much Should He Weigh?

OK so for the nutcase who told you 25-30 lbs, she is an idiot. Your dog would probably weigh that in the first 2 months. My boxer/bull mastiff was anywhere from 80-100 lbs at 2 and is about 110 lbs now that he's 3. We don't expect him to get much bigger than that. Once, he did get down to less than 80 lbs but he had a cold and was not interested in eating. I would say if you're seeing clearly defined ribs, your dog is probably too skinny and if you're not seeing any rib definition at all, then your dog is probably overweight. Regardless of his actual size, don't expect him to realize he is that big. Ours still thinks he's a 10 lb lap dog!

My female boxer weighed 78lbs, and I bred her with a bullmastiff that weighed 130lbs.  She had 11 babies,  7 male and 4 females.  All of them looked liked overgrown boxers, some boxer colored and some white, and some reddish and fawn.  The smallest " Cherokee"  weighed 72lbs.  The largest however "Calijah"  weighs 144lbs. And is an absolute gentle giant and is extremely intelligent.  I.E.  I have to keep the sliding glass doors locked otherwise he slides it open with his bear paw and lets all the others out in the yard along with my A/C.

I have a brother and sister Boxer/Bull Mastiff mix. My female is 75 lbs and my male is 120 lbs. They are 11 years old and are now turning gray around their muzzles. They are also the biggest babies ever, but are very protective of their "house" but will nudge and nuzzle you to death. They are great dogs.

We have a mastiff/boxer mix, he is 11 months and weighs 86 pounds.   We think he will come in full grown at about 110-120 pounds

So we just adopted a dog from a Rescue center that they are guessing is a Boxer/Mastiff mix. So far he has been an awesome baby, only 9 weeks old and cute as can be. Is there anything special we need to know for this soon to be BIG baby.

I have a Mastiff/Boxer cross male pup. He is 5 1/2 months and weighs 62 pounds. I think he will be around 140 at 2 years of age. Mastiffs are a very large breed and purebreds can weigh up to 250 pounds full grown so a mix wont be as big but you should plan on a LARGE dog.

I have a boxer/ english mastiff mix right now as a puppy and she is 8.06lbs. And she is only 6 weeks old. Mine should be larger than yours because english mastiffs are larger than bull mastiffs on average. I have no clue how heavy mine will be at two but 80 or over is what I estimate.

That woman misunderstood your question. A mastiff/boxer mix is a huge dog and 80 lbs is perfectly normal. They can get up to 100 lbs

I have a bull mastiff/boxer he is 3 years and he is 8 stone on the button ,hes a big baby and very one loves him I am a happy owner ,,hes been to the vet on monday and hes 100%

I have one too and she weighs about 85 pounds we call her the little chiwawa because she barks snarls and growls then licks you to death...

I recently rescued a Boxer/Bull Mastiff mix, at least that is their best guess.  He is 10 weeks and weighs 22 lbs.  At 2 years I hope he doesn't fit in my car.

I have a bull/boxer mix, he is 1 1/2 years old. I don't know if he is abnormally large but he weighs about 105. The vet says he is healthy and still growing a little

I always adopt my boxers.  I'm on #3 now, but when he was a pup his head was so much bigger than the rest of his body.  He kept growing and growing. Dozer is now 2 years old and about 110lbs. I am glad to find out he has relatives out there and they are Boxer / Mastiff mix.  My 11 year old Boxer was considered a big Boxer but his "little" brother is a beaf-cake.
What a great combination.  I am a true believer in adoption so I don't think I could possibly be as lucky again to find a mix up for adoption.  Love my pups!

We have a mastiff/boxer. He's 2 and a half years old and weighs 110lbs.  He could probably lose 5 pounds for his optimum weight, but his garbage and kitchen counter raiding habits make dieting hard.
