Does any one know of some one that can make a neoprene dog vest. The largest I have seen is 5x which is for dogs up to a 38 inch chest. My dog has a 42 inch chest now that he has matured.
He wore a 5x until last year now it won't zip up and if it did would be to tight. He loves water fowl hunting but does not have under fur like a full blood lab does. His size comes from his Bull Mastif grandpa.

I think you best and only bet is to contact whoever made the small one, and see if they will do a custom job for a loyal customer.

Benik seems to be the only one but that will do. Contacting them today. Thank you Wytex
