Wholeheartedly agree with you, as a dog owner myself who has put hours and hundreds, possibly even thousand's of pounds in to ensuring mine are well trained, fulfilled, happy and well rounded it frustrates me massively that anyone can own a dog & there is no requirement to train it or be accountable for its behaviour.
Mine is not a dangerous type breed at all, we have a spaniel - a very popular pet in the UK despite being a very high energy working breed, and people honestly do not do enough breed specific research before they take a dog into their lives.
A huge proportion of spaniels that end up in rescue have bitten people (or snapped without making contact) as they are prone to resource guarding. This can be guarding anything from “high value” items such as their food to things we perceive to be low value such as a pair of socks or a tea towel. Carrying items & wanting to retrieve & sniff (hunt) was literally bred into them as a working breed of dog, and yet millions of families get a spaniel puppy with ZERO regard to what they’re bred to do. They then wonder why their dog constantly picks their shoes up or steal the tv remote to carry around in their mouth, all whilst giving them no safe & appropriate outlet to express their inbuilt working “drive”. It only takes a few times of snatching that item back off the dog or telling them off for “stealing” shoes/socks whatever, and the resource guarding then starts. It all could have been prevented if people just understood their dogs and trained them / worked with them in a breed specific way!!!
The difference between a spaniel and an XL is what they’ve been bred to do. The XL ancestry is fighting dogs. Give that to some clueless muppet who wants to look hard, who has no clue about breed specific behaviour and appropriate training and it’s an absolute recipe for disaster.
All dogs should be licensed in the UK and it should be mandatory to have at least 3rd party liability insurance.
