Also, I want a lighter collar, not heavier for my chihuahua. Should I go with the 3/8th size if I want a lighter collar? She is a short hair chihuah

Yes definitely this collar is heavy for my toy poodle and she weighs about 6 pounds. She also has some in the 3/8 width. The small collar is perfect even for a smaller dog. I have it in green, red , silver and prissy pink . The pink is by far the most beautiful. Good Luck!

I would get a medium. I have a 12 pound chihuahua and got her medium. The small was too little.

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 :)

I have a chow with a very large neck. He weighs 75 pounds. I got the medium 22" and added 3 extra links. I do not recommend the heavy one as the links are too thick. There are several videos on youtube about fitting your dog with this type of collar and it explains why this one is the best.

I used a fabric measuring tape to measure my dogs neck. She is an 8 Lb miniature schnauzer. I would say a small to an extra small(if that is an option). The charm didn't last a week but the collar itself is great.

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.

It is a very adjustable collar. My dog only weighs 34 pounds and it fits her but, would adjust to a smaller size as well. Hope this helps you in your decision.

I would order the medium the small fits my toy poodle perfect her neck measures 71/2 inches. This collar is beautiful the prissy Pink aurora is pretty also. I have it in red and green but the silver has the most sparkle next would be the pink. Good luck

I'd probably get a medium. The small sized one will be too small. The medium one will be a tad too big, BUT links are easily removable. I had to take out two for my dog. They simply pinch together to remove. This is such a quality collar and makes training to heel easy-peasy. Remember, be consistant and calm! I tried two other types of collars and got nowhere fast.

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.

This is the review I submitted for this harness under a different color. Hope it helps!:"I have ordered several of these harnesses in the light blue, pink and purple as my mini dachshund has grown and they are all beautiful. They have rich pigmentation and are well-made. They seem to run small, so make sure to measure your pup. My baby girl is 11 lbs now and fits the MD perfectly. She was 4 lbs in the XS (which was a tad loose when we first got her) and 7ish lbs in the SM, for reference. I **highly** recommend them if your concern is a harness that won't pull on the spine, especially for Dachshunds. She has grown up in them and refuses to use any other kind."

Hello Annie I have two small Chihuahuas and I brought 3 medium sweaters they are good quality but way to big for my dogs. They would probably fit your dog if you want you can email me and I can take pictures of the sweaters and if you are interested I will sell them to you instead of sending them back my email is eelwell@optimum.net and my name is Esta hope this helps you Annie😊

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.

Hi, my pomeranian weighs 6 pounds and uses a small collar on the 2nd notch, if you can order an extra small that should fit your pet much better since it is a tea cup breed, hope this information helps, HaGD!

Well i have a mix breed chihuahua and she 18 pounds. The M was WAY TOO SMALL!!!!!!!! Idk if you want to try an XL. But i think they have the size chart all wrong. the coat is small cute. And i still have it until today. Saving it for when she has puppy.

I think it should Fit Because I purchased this collar for my Chihuahua and She weights about 22lbs. Please let me know if this helps you?

The medium size collar will be too big for an 8 lb puppy. You may want to buy a size small or extra small.
