I would get the 20 " because you can always remove a link or two very easily.Hope this helps

You can always buy the large one and remove prongs from it if it is too big. That way if your dog grows anymore, you have some flex room to increase the size. But it is very easy to remove prongs, I had to do it for one of my dogs and it does not change the functionality of it.

I think I would get a medium. My dog has a 14 1/2" neck and I got the medium. His collar has about 3 1/2" left on this one, so you'd be right at the edge of the size, but if you got the large, you'd have a lot of collar left. Hope this helps!

If you can get the neck measurement of the puppy then look at the size of the collars offered for the neck, because you will have to allow for the rapid growth of the puppy. Just be sure to get one big enough to where you won't be buying one every time you turn around.

It says up to 12" for a small dog. Mine is. It gives a slag of an inch or so to make it comfortable. His neck size is about 12" in generous measurement, and he did not mind the collar at all.

That sounds about the same size as my Yorkie and I got the 24". I wouldn't recomend a smaller one for a long trip. It would be hard for a dog to turn around or stand up to full height in a 19".

Personally for a 20lbs dog I wouldn't buy it. They can't possibly have a high enough pain tolerance to ignore other training collars or be strong enough to pull you down the street. I have a 62lbs pure muscle dog. If I were you I would go for a martingale collar. It fully closes around the whole neck which is less stress to the dogs throat and with a quick few corrections he should be in his place.

That question made me look at the original ad for the harness. For the medium harness, it specifies that it works for neck sizes 12" to 17". For the large and extra large size, the spec is 16" to 24" CHEST size. This is clearly incorrect. A 16" chest size corresponds to quite a small dog. They must mean neck size. My dogs have 21" and 18" neck sizes and 32" and 31" chest sizes. The large harness fits them both just fine. My advice is to go for the larger size if your dog has a relatively large chest or if you think it is going to grow.

Hi, For sizing, we suggest to measure snugly pet's neck size and add 2-3 inches to get the proper length. If the neck size is 12 1/2", we will suggest Medium size. Thank you! Amazon Seller: DogCollars

The 20" would be a good size to start out on. The seat post is really long, so if it's too tall, you can always cut the seat post.

My neck is also 18" and the collar works fine. It stays open in the front but it provides traction from sides and back.

I would say 18". Even if he has longer legs the 18" should be big enough. The 20" might just feel a little too big to ride comfortably

According to the packaging information, it depends on the dog's neck size and girth size. I have one of these harnesses in my inventory and it is a Medium.If the dog's neck size is 8"-14" and less than 20" in girth, you would want a small. If the dog's neck size is 14"-20" and less than 28" in girth, you'd want a Medium. Finally, the Large harness is for dogs with 18"-26" neck size and is less than 36" in girth. Hope this helps in your decision-making!

Yes, as long as you buy the PetSafe Deluxe Collar for large dogs. My dog is 94 pounds and has a 21 inch neck. It fits him just fine.

My dog is about 78lbs. I got the XL and it was a little large-I should have gotten a large. Measure neck size & see what's recommended.

my dogs are 80 and 110lbs. The larger dog has a 23" neck, this fits him on the last hole...

You should NOT buy a larger link just in order to get the size around the neck correct. You should use the smaller link and add more of them. For a dog less than 40 lbs. you can use the 2.5 mm size (small) and add extra links, which come in packs of 3. The collar should fit snuggly; otherwise, if loose, it will irritate the dog's neck and you won't be able to make a gentle correction.
