I have a French Bulldog she weighs under 30lbs and an XL fit her. The tag said it would fit 46-70lb dog but this would not fit a dog that big. Overall it worked. It's cute but it wasn't worth $16. It's just regular t-shirt material, fairly thin, and screen printed.

I bought this for my French Bulldog that is about 25lbs and my mix breed that is about 40lbs.  While The mix breed is fine, the Frenchie started spazzing and zipping around the apartment trying to scratch herself on everything within an hour of application.  This would be great for my larger dog but after googling it seems that this product is just NOT GOOD for smaller dogs.  I bathed my Frenchie to get the product off of her and gave her some Benadryl so hopefully she will feel better in the morning.  I only bought this because it also protects against mosquitos which we have tons of in Charleston SC but it was NOT worth it... I would not buy this ever again.

UPDATE: Both dogs have scabs down their back where the product was applied.  Thankfully after multiple baths and a few days of benadryl my Frenchie is back to normal. She also has fleas again so we are getting a new product from the vet that won't have such a negative reaction with both my dogs. Seriously... talk to your vet before you buy this!!!

I bought a medium for my currently 22 lb frenchie, when he was about 12 lbs. When I got it it was very long on his body, but fit over his head and shoulder and I was concerned that as he grew, the length would be right, but the rest would be too small. Happy to report that at 22 lbs it fits him perfectly in all areas.

I put this on my English bulldog food and she loves it. 1 pump for every 25 pounds. It had helped with her shedding.

My Maltese weighs about 8 pounds and the small fit her. So Cute. I did add a little more veil fluff.

Seemed more comfortable for my dog than the plastic ones. I got the medium for my French bulldog, it fit but it was almost too snug. Luckily there were two strips of Velcro to choose from to secure. Got the job done.

I have a 3 lb yorkie who will be 14 this year and she is having problems going up and down the two stairs we have that separate our living room and dinning room. I just received this item on Friday and she was really scared at first but I put treats along it and had her walk up and down it about 3 times and now she walks up and down it with no problems. I am very happy with this item. However, I read other reviews with larger dogs and it being flimsy. I did try walking on it to show my dog it's okay and I am only 130 and it was really wobbly and not sturdy. I could see why the larger dogs would be afraid of it. I disagree with the ad saying it is okay for up to 200lbs.

I have a 30lb mini bull terrier and I accidently bought the large. It did end up fitting him on the smallest setting but he broke the clip less than a month after wearing it!! I'm so bummed because he looked great in this collar but the quality I guess isn't there. There is no a way a 30lb dog should be able to break a collar and take off that's made for a large dog.

I really like this harness, but the proportions don't fit my french bulldog very well. I have this in both a small and a medium (since I have a growing puppy), and neither one fits quite right. The small is quite snug when going over her head (which is a problem when I'm trying to take it off), but it fits perfectly once it's actually on all the way. I tried the medium on my frenchie and it goes over her head fine, but it is huge on the rest her to the point her front legs don't stay where they are supposed to.

I suppose this is a great harness for a dog with normal portions, but not great for my frenchie. Maybe I'll give this brand another try later when my puppy has grown up a bit more.

I have a French Bulldog who is so smart that she gets bored without a challenge.  This was the perfect solution.  I can fill it with small bits of treats and place it down for her.  She is entertained and rewarded at the same time.  The construction is sturdy and the extra little "bone cones" provide additional challenge.  I highly recommend this product.

I have a small dog but she's well within the recommended size/weight.  Her barks ares higher in pitch so they don't register and therefore the devise doesn't spray.

My dog is around 30 pounds.  This is her favorite... and mine.  Really well made, strong and a great size for tug of war.

This is amazing, and just as I expected!! So cute!!! I have a 25lb. french bulldog, and the XL was definitely the right choice size for her. I would say it runs a little small, so order up.

My french bulldog had this collar already so when I got another french bulldog I had to get another. Very well made collar and perfect for my bulldogs.

This is really nice, I got it for my girl pit mix she is 54lbs and there is still room to loosen it in case she gets a fatter neck.

My frenchie loves it! I got the medium one which is perfect for his size. I'm glad he loves it;)

The steps look nice and are very cushiony.  I had to return mine because I have a 75lb lab and the steps are too light for heavy dogs.
