How Much Should a Staffy Weigh? [STAFFY WEIGHT CHART]

You will need to maintain your Staffordshire Bull Terrier at the ideal weight range for them to enjoy a long and healthy life. Staffordshire Bull Terriers that are under or overweight can be susceptible to various health issues. So, how much should Staffordshire Bull Terriers weigh on average?

What Is a Good Weight for a Staffy?

The Kennel Club and the American Kennel Club (AKC) classify all Staffies as medium-sized dogs even if they fit into a pretty wide weight and height range. Most dog breeds (but not all) don’t grow any taller after their first birthday. However, dogs will continue to gain weight, and you’ll see their bodies significantly thicken until they reach eighteen months to two years.

Staffordshire Bull Terrier Ideal Weight 

Staffordshire Bull Terriers are available in various sizes when fully grown. A male Staffy stands 14-16 inches tall and weighs 25-38 pounds. Female Staffordshires stand 13-15 inches tall and weigh 23-35 pounds.

Amstaff Ideal Weight

You probably realise the Amstaff (American Staffordshire Terrier) is considerably more significant than the Staffy. A fully grown Amstaff grows to 17-19 inches tall, at the shoulders, and weighs 50-80 pounds. 

However, the females, like the Staffy, will be smaller. Female Amstaffs are typically 16-18 inches tall and weigh 40-60 pounds. 

As you can see, there’s a good two to three inches difference up to the shoulders of both dogs; add in the neck and larger head, and you can tell the Amstaff is the bigger dog.

Average Weight of a Staffy

It’s a fact that breeders are creating much larger Staffies these days, but notwithstanding the average size of a Staffordshire Bull Terrier is 31.5lbs with a height of 15 inches. Now that doesn’t address the trend in breeding larger Staffies, which seems more prevalent these days.

Females are always a little smaller than males, with an average weight of 29lbs and an average height similar to males.

How Do I Know if My Staffy Is Overweight?

Overweight Staffies, and all dogs, is an increasing problem for even the most diligent pet parents. With obesity comes an assortment of severe health issues. While it’s best to prevent weight gain in Staffies, it’s never too late to begin a weight loss programme.

You should be able to feel all of your Staffy’s ribs without a thick layer of fat covering them, regardless of the dog breed.

The Staffy’s chest should be wider than the abdomen, with a visible tuck-up from the chest to the stomach. This would typically be even more pronounced on a Staffy because of their larger-than-average chest size. An overweight Staffy usually has no waist and no separation between chest and stomach.

How Do I Get My Staffy to Lose Weight?

Overfeeding and lack of exercise are the primary causes of obesity in Staffies. If your Staffy eats lots of snacks, table scraps, and large portion sizes at mealtimes, they will put on weight, especially if you don’t exercise them as you should. 

If you see your Staffy is overweight and want to do something about it, make sure that you get your Staffy checked out at the vet first. Once your vet gives you the go-ahead, take it easy at first and give your Staffy a chance to build up its stamina again. Don’t push too hard in the beginning.

Please switch to a healthier brand of treats and ask your vet for advice on portion control and the dog food they recommend.
