Love this harness and how great this company was to help me get something for my dogs birthday despite the current state of our country! My dog is a 6Ib Papillon who normally runs as an XS. She is 13 and has neck issues so the XS ended up being too small and bothersome to her but this company was great on letting me exchange for a size up and the shipping was super quick both times as well. I highly recommend sizing up if you have a dog with neck issues too as it's not adjustable around the neck (is however adjustable around the back) and the sizing chart while pretty accurate did not account for these things. The new size fits more comfortably and she is getting used to it as it's been a while since she's gotten a new one. Who says you can't look fabulous in quarantine.
This fits my Boston terrier great! She looks too cute as well!!
