Teko Dd: How much should an English Mastiff weigh at a year old?
I know it matters on their parents but I have a mastiff he's 12 months old around 150 lbs.
How much more is he going to grow? What is the English Mastiff puppy growth chart?

Boys can weigh 150-200 pounds. He'll probably continue filling out for a bit yet. Up to 18-24 months.

There's no way to know. All dogs grow according to individual growth rates, and there can be huge variety among the growth patterns of Mastiffs. Some grow rapidly and their weight hits a plateau at a young age. Some grow slowly until they're four years old. Some have random growth spurts. There's no way to know if your boy will soon hit a plateau and end up being only 175 pounds, if he'll gradually gain weight until he's 220 pounds at age four, or if he'll have unpredictable growth spurts and be, say, 200 pounds. Knowing the growth patterns of his relatives can definitely help to guess your own dog's growth rate, although it isn't a guarantee.
There are a few growth charts for Mastiffs on the internet. They must be taken with a grain of salt because many happy, healthy Mastiffs do not follow them. According to one of them, a twelve-month-old male would be 175 pounds and would be 220 pounds by age five. With that reasoning, your 150-pound boy might be 195 pounds when he's completely done growing.
Anyway, although as you know, this is completely unguaranteed, I think he'll end up around 200 with a ten-pound leeway both ways.

Our English Mastiff weighs 241lbs and seems to be in great health according to his Vet and his behavior. He is full of energy and loves to play but he also loves to sleep. He is by far our favorite dog we have had over the years. We gave had German shepherds and Rottweilers and Gus is the best behaved and least aggressive but by far the largest. I would recommend a Mastiff to anyone looking for, a dog.

I have a 19-month-old male English Mastiff his last vet visit 1 month ago. He only weighed about 129/130. However, his mom and dad are 2xlg. I'm wondering why is he so small.
Will he get 170/180 and is this not good? On their hips and legs to gain weight. After there over the puppy growth. On my mastiff, you can distinguish his hips to the start of his rib cage long chest, and big blockhead.

My English Mastiff is 196 pounds at almost 12 months, I just did two size calculators on English Mastiffs and they say he’d get to about 226 pounds. One growth chart said also that he was near the top of the weight scale for his bread. Seems that yours is on the lighter end of the scale.

Hi, I was wondering if it’s normal for our four month old male English mastiff to only weigh 41 lbs, he’s been gaining on average 15 pounds a month but that still seems small to me.his dam died during whelping and him and his siblings were bottle fed but his sire is 220 lbs.our previous mastif f Ramsey was 175 lbs but we adopted her as an adult, and I remember our first saint Bernard mojo was 21 lbs at eight weeks and saints are smaller as are females, our pup was only 14 lbs at eight weeks.our get says he’s healthy but that we shouldn’t let him gain so much weight in a month even though I’ve read they can put on 2 lbs a day during their growth spurts.

It seems small compared to the English Mastiff growth chart but every puppy is unique – one grows faster, another slower. Your pup was small from the very beginning but it doesn’t mean he will remain small when he becomes an adult. The most important is that your vet says he is healthy. Don’t rush with getting weight. Little by little your puppy will get what he should get.

Our Old English Mastiff (Sir Hektor Otis-an Apricot) weighed in at a healthy 247 at 4 years old. Unfortunately, two mean teenagers in a car shot him twice while I was walking him around the block (with a pellet gun). He was 7 1/2, and the best, most mindful, protective, sweet baby! He loved children. We had him at our service staion every day since he was 7 weeks old. He was very socialized as all mastiffs need to be., and they crave to be close to their family. We took him to Purdue U Vet, where he had surgery. These big dogs do not take surgery very well. The Vets said they were amazed at how healthy he was after looking at the X-Rays and test results, especially for his age..”.just had the normal slightly enlarged prostate as most 70 year old men have” was their statement.He lived 5 days..the love of our life! We miss him terribly. It seemed the only way to get past this was to get another. They are smart, can be defiant, argue with you, and are very powerful. They need to stick to a regular diet-not people food, and you will have an amazing attention-getter family member!

Sorry but I do not believe any healthy 1 year old mastiff being 175 pounds. Either people embellish about the weight or the dog is just over fed and fat.
Lyla says
I have a healthy lean and muscular 275lb English mastiff. He is not fat and will still continue to grow. His mom was 200lbs and his dad was 220lbs.
