On our walks over the last month, we've picked up 5 lost dogs, and been able to return them to their homes, thanks to collars with phone numbers. We've decided to call June lost dogs month.
A friend of ours lost their dog this month, hit by a car after it had escaped. If you happen to see a doggie by themselves, do try to pick them up, they usually have no road sense and can be hurt easily.
Cute as a button, lovable and cuddly as well
If they have a collar it is easy to contact owners, or failing that, a trip to the vet or as a last resort and you absolutely have to - the pound will find their owner, if they are microchipped. Should the dog appear dangerous, certainly don't try to approach it yourself, but a call to the pound or council, and you will have someone out to assist.
