My dog is a 15 pound Cairn Terrier. DoI need a small or medium harness?

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.

Since your dog is at the max end of the size Medium, my advice is to contact Horgan Harness to discuss the size, shape of your dog for a recommendation. You can e-mail or call 954-789-9580 (9A-3P). I emailed them and got a response the next day.

Great harness very sturdy. My dog weighs 65 pounds and it fits him great, he wears a medium. I highly recommend it and it's adjustable.

I have a dalmation mix about that size and the large is a perfect fit. I also have got the tether to anchor the harness to either the tie down in the back seat or the seat belt in the front. The harness has a range of adjustments and fits well. Betsy wore hers almost constantly a couple summers ago where we traveled across the country. She never had any problems with rubbing.

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 bit hug for me.

My dog is about 15 pounds. She is very active and this harness holds her very comfortably and happily. There is also plenty of growth room in the harness itself. SW

If you add it to your cart, it will say medium. I purchased a medium for my dog who is around 40 lbs and it fit perfect. I am very happy with this harness. It's sturdy & she can't get out of it & she got out of most of the others.

I got my 5lb Yorkie a small, but my 16lb Cairn cannot wear the medium, it was too big for him and the small was too small. I made him one myself. There is a little bit of "give" in the Small. You could try that on a 10# and if it doesn't fit send it back.

the medium is a little bit big for my 5 pound dog - so i would get the smallest one would work just right for you.

The small fits dogs with a girth of 16"-20" and weight of 15-25 lbs. The medium fits dogs with a girth of 21"-27" and weight of 20-50 lbs. The small will be a better fit for your dog and shouldn't be too snug. The medium may be too large and not provide the proper support.

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.

depends on size and length of your dog as well as size. I have a welsh corgi, medium length is right because his body is long and size is good, but straps could obviously fit a dog that is heavier.

I would get a X-small because in the details of this specific size it states "For dogs with a girth of 15-inch-19-inch and weighing 11-18-pounds" that goes in correspondence with the girth and weight of your cairn terrier! It is true to the size. I purchased a Large for my 40 pound dog and in the details for that specific weight it said "For dogs with a girth of 26-inch-35-inch and weighing 40-70-pounds." The weight is all I went off of at the time due to not know what his exact girth was. It fit perfectly for him!

My dog weighs 16 pounds and the medium just fits. If you dog is longer than 15 inches from nape of neck to base of tail it will be too small.

I'd get a small. I got a large for a 50 lb. bulldog (NOT EASY TO FIT) and it's perfect. You can adjust them pretty well and easily. Best harness I ever bought!

Medium - Harness best fits pets with breast girth 14 to 17 inches and neck girth 8 inches. Leash is 46 inches in length.It might be too tight for on the neck.
