The old Canarian law (2004) states that dog owners must ensure their pets are on a leash,
collar or breastplate or muzzle whilst being in PUBLIC areas.
The owner must also carry a bag and a shovel for the collection of animal droppings.
I presume the shovel means a poop scoop or similar.
Amongst the dogs that are considered dangerous and must be muzzled in public are...
Bull Terrier, Bull Mastiff, Staffordshire Terrier, American Bulldog, Pit-bull Terrier,
Rottweiler, Great Dane and St Bernard.
As for microchips, these should be compulsory as they can help locate lost dogs with owners
and indeed owners of abandoned dogs that are often disregarded like unwanted trash.
