What a relief he's home - must've been frightening!! Delighted for you
Our collie once took off after a car on a walk many years ago, a couple took her in, rang the number on the tag (landline) and as everyone was out looking for her it just rang out, so instead of holding onto her, phoning the dog warden etc they just let her back out onto a busy road!! We found her absolutely shattered in a bus shelter but luckily unharmed.
Just a thought - I've just bought 6 collar tags on Ebay as mine loose theres from time to time so plenty in back up. It worked out soooo much cheaper than other online stores, I think it was £6.50 for all, engraved, inc postage.
Enjoy the rest of your Bank Holiday
