This is a very cute Jacket/Coat. Excellent for a very tiny dog. Is like a XS. Winner pay exact shipping costs. If you place a bid and after that don't want it then I will retain your credits. I'm not responsible if the jacket don't fit your dog. This was my baby jacket when puppy.
I'm not an expert taking measures but here are them in inches.
Chest: (circumference) 13 to 13.5 inches Back: Measure from collar to part more long in the back. 8 to 8.5 inches Neck: (circumference) 11.5 ti 12 inches
Also I take the measures with a Measuring tapes that is more rigid than a fabric measuring tape. The measures are from the jacket/coat/parca, so you have to leave a little room from your dog.
By the manufacturer of the jacket, it is a 8 so your dog measures must range between this:
Size 8 Neck 6-8 Girth 10 to 12 Length 8"
The perfect size 8 is 7 1/2 neck, 11 1/2 Girth and a length of 8
Not sure. My dog is a mix of chihuahua and Shih Tzu and this fit him when puppy. I can try to measure it. By the photos you can see is tiny because in some of the photos I used a can of Lysol to maintain it up. Write you later with the measures.
