Which size would be best for a 40-45 lbs. Staffordshire Bull Terrier?

I have a 45lb American Pit Bull and the large fits her. Since bully breeds can sometimes have wide chests, I measured my dog's chest girth, neck, and back then went to the Outward Hound website to look at the sizing chart to find the best size. The website says the chest girth is the most important probably because the chest straps have the least room for adjustment. Good luck! It's a great backpack :-) http://www.myoutwardhound.com/2490.html

I believe it is the medium. That is the size I bought for my sons beagle who weighs 45 lbs. At first he thought it was too large and found it was not when the pockets were used. Hope this is helpful.

I purchased an XL for my 7 month old English Bulldog. They key measurement is the chest. I would say a medium may work for a Boston Terrier

I have an extra small for my 4 lb yorkie and a small for my 6 lb. I'd say either medium would work. A snug fit is better than a loose fit.

I would get the Medium size. We have a 30+lb Beagle and the medium size is just perfect for his paws. It works really well!

Assuming it is full grown, I would say a Medium. That is what my 50lb terrier wears.

I have a 186lb English Mastiff and have the XL. My ex-wifes English Bulldog is only 60lbs. So splitting the differance, I would go with the medium.

Agree with the others, go with a bigger one. I have a 45 lb lab mix and it is bug enough for him to curl up and stretch out. Double him, and I would say go for the 52".

If its very deep chested I might recommend xl if its not to deep then maybe large. I have a 72 lb American bull dog mix and large is good for him but his chest is not very wide for a bully breed and not deep at all ... Really it's all about the chest as the pack its self fit him in a medium but the chest strap was to tight.

I would suggest the medium. I have an 85# yellow lab and it works great on her.

I would get the xxl. My dog is 70lb Aussie mix & that size barely fits her but I think that's as large as they come. Diaper area is plenty large enough, but the waistband is snug.

My dog wears a Large and is 50 pounds and 28 inch girth.. I'd say go with XL

I would say a medium or large. I have an xtra large for my Saint Bernard and that would be too large for your needs.

I would get the large, I got the XL for my olde English Bulldogge and his girth is 34 and there was still about 6 inches of extra space on the tightest adjustment!

I think the medium would work great for your pup. Mine weighs 11 pounds and can lay down if she wants.

My dog was 47 lbs and she wore the Large size and she had room. I think for a 35 lb dog medium would work well.

I would suggest a medium as this harness is adjustable. We have been using the medium for our dog for over a year now, and she has grown from approximately 30 to 45 pounds in that time frame.

Based on my experience, a medium might be the best option. My dog is a lab mix. She's about 65 lbs, 31" chest, 22" waist. The medium size fits her quite well. I've adjusted the harness so it's just a little bit loose on her; there's still enough room to expand the front harness by 3 inches or so around the chest and the rear harness has enough room to expand by about 11 inches around the waist. The rear leg straps are adjusted as big as they go and they were just about right for her; the circumference where her hip connects to her body is about 19". I've since started using the harness without the rear leg straps as my dog recently had one of her legs amputated. Even without the rear leg straps the harness works quite well.
