The vest is great unfortunately the size was to big for german sheperd.
Size guide is great and true to description. I ordered a medium for my cocker cross 15kg 58cm chest 38cm neck. A little loose on the neck but with the fur I think that is a good thing. The back has 2 zips to adjust for size as well as a elastic tie to tighten and has a built in harness which is brilliant for walking. For the test walk, we carried it in our bag to start and half way through the walk pup was getting tired and hot, so we poured water and squeezed out the extra, within minutes pup had a bounce in his step again and the panting had reduced considerably. The water stayed in the jacket for quite while too but would also depend on how hot the day was. Definitely recommend this product, we have a heatwave due next week so will be trying it on then as well. Thankyou
