Purchased an adjustable ID collar in Forest Green for my 6 month old Border terrier. It is a nice lightweight collar and I really like the unobtrusive engraved ID tag rather than a dangling metal disc. I prefer to use a slip lead so the collar is simply to fulfil the ID legal requirement. Bettypoo is a good company to deal with and they contacted me several times about various details to ensure everything was correct. Because my dog isn’t fully grown I went for the adjustable collar but I think once he has stopped growing I’ll get a bespoke ID collar for possibly a better fit. At the moment because he is at the lower end of the size range the collar adjustment overlap is quite large so the collar isn’t quite round on his neck. As he grows and less adjustment is necessary I think this will rectify itself. Would certainly recommend both the product and the company and will buy again.
