I have a 9 lb. chihuahua with a neck size of 9" and a chest size of 13", but her back length from base of neck to tail is 17". What size do I need?

My CC is approximately that size and I bought her a medium and it fit perfectly. However the pj's did shrink some when washed & dryed.

I ordered a small size by their measurements and wish I had gone up to medium. They were too small and tight for my dog. I had to give them away to someone who has a smaller dog. I have a yorkie.

I bought the medium for my toy poodle and it fit perfect. You may want to buy the large.

We have an 8 pound chihuahua and it literally falls off him. However your talking about 18 pounds vs 8 pounds, so I would really say no, you need a medium.

I'd say no bigger than a medium. I bought a small for my long-haired chihuahua. She's about 8lbs and it fit her perfectly.

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

I bought my collar for one of my dogs who weighs about 15 lb. I don't know what her neck size isbut it fit her just fine with adjustment. I think it would probably fit a 14 in. neck ok.

I have a medium and it fits my 10 lb Chihuahua with a bit of room to spare. A medium would probably work for you.

I would say that a medium would probably fit better. My chihuahua is very lightly framed and fills up a small nicely. Most of the mini Dachs that I've seen have a robust chest and well sprung ribs so your baby might be a bit snug in a small. This shirt doesn't have a long torso fit either so the medium would cover his back a bit better. Zack and Zoey is a line carried here on Amazon that has that longer torso fit which might serve you better for the breed.

Don't know --You need do the measurements. Neck to tail is the most pertinent. My dog is 18lbs., and 17 " neck to tail.

I purchased an xs for my chihuahua and it was to big. I tried it on my dachshund but it was to small. So, I would get a size medium for a standard or a small for a mini dachshund.

I got the extra small for my Chihuahuas. They range in size from 5-8 pounds.

What kind of dog? I have a 4lb, 8 and half month old Chihuahua. I ordered the small and returned it. I'm happy with the medium. Cortez will not get much bigger. I can assure you if you get the wrong size the return is simple quick and easy. Please let me know if I can help any more. joanne

It fits my great dane and he's 42 inches around the chest and 22 inches around the neck so she should be fine! :)

If your dogs neck is 18 inches you should probably consider going with a large. My dogs neck is 14 inches and there is no room for growth, so a large is definitely the way to go for your dog.

Measure around the largest part of their chest (girth) and that should give you a proper fit. My Yorkie is a little over 13 inches around so I ordered the XS. It fits her quite well. I also checked the Thundershirt website for a measuring chart, just to make sure. I found that the girth is more import than the weight of the dog. I hope that helps you!

You'll probably have to contact the seller. I purchased the item for a friend and we took measurements, then looked up sizing for dogs on the internet. Sorry I can't be of more help.
