M size is running a little too tight for my 3,9kg York. I should have chosen an L size, but for now, this one will do. As long he doesn’t get any bigger and it fits him.
Great suit! Arrived in the US in 20 days, which is very fast for the pandemic period. The quality is excellent, inside the fleece lining. On Chihuahua 3.2 kg and 28,5 cm on the back, the size L came up well. I recommend, thank you :)
