A friend of mine has two Border terriers, both adult. I want to buy my friend two dog collars / id tags/ leads etc for his dogs. I have found the collar I want to buy, but I am not sure which size to get.
I have never had a dog before and I don't want to ask my friend which size to get as I am sending this to him as a suprise. I have included a pic as a size guide if anyone can help?
Thank you
