I have a french bulldog-thick around (23 lbs) short from neck to tail. It seems that the harnesses that fit around are always too long.

I have a mini-pin/chihuahua mix and she is about 20 lbs with most of it around her shoulders. The bottom strap is adjustable so it fits well in the shoulders and can be adjusted for the middle. I don't think it is too long for my girl. I know it's a pain but if it doesn't fit, you can always send it back.

The straps are Velcro and very adjustable, I have a Boston Terrier (which is the same height but a bit slimmer than a Frenchie) and I bought him small and have to adjust it tight, it fits him prefectly. I would recommend the small for a french bulldog. I hope you have fun and safe swimming with your grandpup. Remember to keep his ears and nose above water!

I bought the smallest size of this harness, but our pup (a toy poodle - bichon frise mix) was too small. She is now about 20 pounds but I haven't tried it on her recently. It seems from other comments, everyone is finding this harness runs big.

I would think so. I have a 20 lb long haired doxie and I bought a large, based on the dimensions of the harness. It is perfect for my dog with room for adjustment. Measure your pet and choose the size. It's a very nice harness.

I would probably get the small one since it runs true to size. The medium girth is 21-27 and that's to big for a bichon. i got a lg for my bulldog and it fits but a medium would have fit snigger on him. Good luck

I purchased a "small" for my 8 pound Silky Terrier. It fit relatively well for that size/weight. However, she was very bothered by the straps around her back legs/groin area and wouldn't walk. When I pulled on leash, her back end went right up in the air...so did not work out for us. A larger, heavier dog will likely be more adaptable to this style. Good luck.

I believe this depends on the weight and size of your dog. For example, a dog over say 30lbs would be more comfortable with a wider 1 inch harness so that It does not dig into his fur and cause discomfort. My dog is 55 lbs now and I use the 1 inch harness. Anyone else have any thoughts on this?

I have a 20 lb Pekingese and I bought the medium harness. It was too big. I would go with the small harness.

It was recommended to us to order based on the length of the dog (from withers to dock of tail). We thought our dogs would be very hard to fit this way because they both have very unique body shapes, but it worked out very well. Like the other answer said, I would recommend using the harness under the jacket rather than over it. If you put a harness over any kind of clothing, it can cause the fabric to bunch up and irritate the skin.

This one should work better. I had the same problem as you. I ordered the small for my mini dacshund and it was to short. So I ordered the long short and the neck width was still perfect but the snout length was much longer and prevented her from getting to her tail & back legs.

with my 22 1/2 pounder I checked into dog harnesses, they don't have the velcro security I feel I have with the ones made for cats, if you can find one made like the kitty holster instead of just straps, measure girth and neck size and go to a pet store and see if they carry the vest type, usually all they have is for little tiny dog.

First of all, love this harness! Will she get any bigger? I ordered a small for my then 6lb shih-tzu and it was perfect! She is now coming up on 8lbs and I see the neck opening is getting a bit tight & I may be ordering the medium soon. Also take into consideration that shih-tzus are bulkier than poms so your baby's neck might be thinner :)

Both of my dogs are between 15 and 20 lbs, so am not certain. I do think, however, there is room in both harnesses for a considerably larger dog.

Personally I would not get it for dogs under 20 lbs because of the heavy metal square that keeps it together. If you are okay with the metal square, I would do a small for the bichon and medium for the rat terrier. My mother has an 18 lb. rat terrier and did not like the harness because of the metal square. You can't see it in the picture, but it sits on their back where it all comes together. I think it is a good harness for dogs over 20 lbs. I hope that helps.

It really depends upon the size and muscularity of the dog's leg. I'd measure around the dog's leg, just short of the body, add an inch or so to that (to ease putting the legs through the harness) and then choose the harness that comes closest to your measurement. You might check on the company's website - you can ask them which would fit best based upon your measurements and they'll get back to you with the appropriate size. Good Luck.

I think it would be best for you to contact the seller of this harness. I no longer use the harness. Previous answer by David is excellent. Give that loving doggie a big hug and kiss for me.

Personally I don't think this seat would be suitable for your French bulldog. My dog is 11bls and she takes up most of the seat. She is a Shih Tzu. I also have an "outward hound" car seat which is a lot bigger and more sturdy. I hope this is of use to you
