All my critters are chipped.
Not because they are dangerous (they aren't, unless a cognizant trainer tells them to be in the case of the police dogs & horses, and my two "attack" Skogcats, and the brood mares), but rather because I'd like to get them back if they are lost, stolen, or strayed.
We carry a US$5,000,000 policy against accidental injury by our critters. As professionals, it only makes sense. It also only costs us ~US$85/month ... but then we're professionals, and we have an excellent track record.
Idiots with no clue about animals who allow what would otherwise be a happy, healthy pet to strike out at (seemingly[1]) random need to have all animals removed from their possession, permanently, and receive a hefty fine ... with a guarantee of jail time for a second offense. Said removed critters should be evaluated by a professional, the ones that can be rehabilitated should be given a second chance. The ones that probably cannot should be euthanized for their own sake.
Try to remember, the "Our Gang" ("The Little Rascals") dog "Petey" was a Pit Bull ... until a couple of high profile cases that were mostly tried in the media in the 1990s, the American Pit Bull Terrier was known as a family and kid friendly dog. Strange thing is, they still are kid friendly, when given the chance ... There are no bad dogs. Only bad owners.
Probably the worst thing that ever happened to canines, especially, is the completely ignorant mass media looking to sensationalize whatever they can sensationalize in order to sell column inches ... Looking to the Press for information on critters is roughly similar to asking the average politician for mechanical info on your car.
[1] It's never random in the case of so-called "domestic" critters ... the animal was always taught to exhibit the behavior by humans. That is ALWAYS, with one exception ... that one exception (that I'm aware of) is canine parvo survivors.
