I am getting a male BullMastiff in two weeks when he is ready to leave his mother. I have a two year old male St. Bernard who is very good natured and has an excellent temperment. Do I need to anticipate any problems with the same sex aggression male/male? I read an article stating that a male bullmastiff will attack another male dog and I am concerned about this.

No, if the Bullmastiff grows up with the St. Bernard and learns to trust him, they will be fine. When you introduce them try to keep them in neutrul ground, away from sleeping quarters or food. And make sure the St. Bernard knows he is still top dog until the Bullmastiff grows up.

How much should my 11 month old male weigh?

We have a year old Bullmastiff who started develping crusty rashes on his skin and losing small patches of hair about 4 mos ago, we brought him to the vet, who ran tons of tests for mange and other infections which all came back negative. She had asked if anything was new to the diet or environment he's in and we couldn't think of anything. We gave him all the allergy and skin pills she gave us in peanut butter as everyone recommends and the rashes flared up, turned out we had started him on some new PB treats and thats what it was a PEANUT BUTTER ALLERGY! Has anyone else heard of this typical to the Bully breed??

I have an 11month old bullmastiff male, healthy and active weighing in at 100lbs ; is that the norm/average ?

The AKC states the normal Bullmastiff should be 110-130lbs full grown. However there isn't a standard to compare year-old dogs against, if your Bully appears to be healthy and active chances are he's normal weight. There are going to be males who are only 75 lbs at a year and some like ours who was 135lbs at a year (both can be considered ideal based on lineage). Typically they will continue to grow even beyond two years, at a year he should be showing max height but will continue to bulk up with muscle. Happy feeding!!

I presently have a 9 year old springer, who is very babied but usually get along well with other dogs. I am concerding adopting a 9 mon. bullmastiff. Do I have to worry about them getting along?

As long as you introduce them properly, they should do fine. I would be more worried about your springer getting along with the Bully rather than the other way around. We have a 14Mo old Bullmastiff who is best friends with our Maltese!! We introduced them when he was 3mos and the maltese was 6yrs, she was very upset with us at first but took to him almost right away. Just be sure to allow for time apart especially in the beginning, and keep in mind the pack mentality that they often work things out on their own. Bullies are known for being great with other dogs and people, but the more you find out about the new dog, the better. You know your springer, so trust your instincts!

Ok this is a simple question my bully was underweight i have started to give him a pint of full fat milk everyday aswell as 3 kg's of dry food every couple of days he gaining weight now but i want to no if the milk is doing him harm?

what would the average size of my female bullmastiff be at the age of 6 months

Mine is 79lbs at 8 months and was 59lbs at 6 months.

Mine is 9 mo. and 75lbs

Mine is 6 mos. and weighs 70lbs.

Mine is also 6 mths and is 48 pounds.

mine is 45 pounds right now and the vet says it will be 100 pounds

I have a beautifull 9mth old bullmastiff, but i think he might be a little smaller than what he should be, can u please tell me what the average weight and hight is for a 9mth old puppy, thanks

Not sure. Mine is from a litter of 11, which i think makes a diffrence. I keep thinking my boy is on the small side at:
9mo. old
75.4lbs.
23" at sholder

20 to 24 inches
30 to 45 kgs

hi i have a 7 month old male bm he weighs 92 pounds but looks kind of slim he eats lots buy runs alot he is very active does 92 lb seem right?

Be sure to check out his lineage if that information is available to you. If he came from a sire and bitch who were both large examples of the breed, his being 92lbs may be normal for that blood line-for example one of our Bullies was easily 80lbs at 9mo and is very healthy now at 2 yrs, with no growing pains. Some breeders may say to cut back on the food, but it sounds as though your Bully is active enough to handle the recommended amount food your brand suggests, just be sure to break feeding down to twice a day and not all at once.

92 lbs at 7months is over weight you should cut the food back. Don't be in a rush to make him big this will cause problums for him in the future if they are over weight. Keep your bullmastiff on a diet and he will be health and will most likely live longer.

what people seem to forget is that these "giant" breeds grow much slower then an average sized dog. feeding 5 cups of food at one sitting is far to much food to put into the stomach. do a little research on bloating and you'll understand why. with these "giant" breeds several smaller meals through out the day is the general recommendation. these dogs can grow well past 2 years of age, the important thing is to provide high quality foods, high in protein.
~and also lets not forget that although these dogs are heavy boned, they're going to have to keep carrying that 100+ lbs into their geriatric years, not every bully is meant to weigh in at 140lbs. a slim athletic build is not always a bad thing.

I have a bull mastiff he is 22 mths he has boils on both of his hind legs what can i do about them and what causes them

I have a BM he is 8 months old. His back is 35 cm. And the front has not caught up yet. Im concerned with his back and hips. Is that normal to be that tall and he cant stand for long. He would rather lay down. He eats 2 meals a day 5 cups in the morning and 5 in the evening. He's not over weight. He looks under weight in the back. In the front its fine. By his tale the bones are sticking out. Im wondering if thats normal or if he has hip problems. He doesnt like to sit for long either.

my bullmastiff is 10 months old and his bottom jaw is covered in boiles and are starting around the top of his mouth what can i do about this?

Hey we have a bullmastiff aswell and he would also get puppy acne around his mouth. I would wash his face with a cold facecloth & just put a little bit of witch hazel on a makeup removal pad and apply it to his acne (boils). We did that together in the morning I use it as a toner after washing my face and it was awsome how fast it cleared up the dogs face maybe thats why I don't have acne myself :)

Our 11 month BM had the same issue. For him it was acne. Our vet told us to use listerine and swab the area 2 times a day for 2 weeks. It cleared up right away.

possible allergic reaction to his dog bowls.... Use only stainless steel bowls - NO ceramic or plastic... will take a few weeks to clear up.....
