People who bring dangerous breeds of dogs on walks in public areas, without keeping a leash them.
Pet peeve, there's not really any such thing as a "dangerous dog breed" - there are absolutely dangerous/poorly-trained individual dogs, but that is not breed dependent. Walking a dog without a leash is one of those things where you have to 1) have the dog under control and 2) take other people into consideration, though. Again, not breed dependent. People who are afraid of dogs probably don't care
that much that the off-leash dog they have to pass on the sidewalk is a dachshund and not a great dane.
A strategy that I used to make people understand was this: I compared feeding low grade kibble to eating fast food. Yeah, they'll eat it and like it. Yeah, They can live on it. But it's not good for them. It's empty calories and doesn't have what they need and they'll eventually suffer for it. Shit food has the same effect on them as it does for us.
So much this. I managed to turn my housemate from grocery store kibble to good, grain-free kibble for her dogs. Surprise, surprise, they actually eat less of it (because they need less) so the end difference in cost isn't so bad. I'm not going to rag on her for having fed that stuff, though; if you're willing to learn and change, you're not a bad pet owner in my book.
My Dad though... wow. Once bought a giant sack of kibble for the stable cats that was probably 75%+ grains. And then he wondered why the cat I took indoors and started feeding decent kibble got a glossy, healthy coat in the span of a few weeks.
Atm I feed one cat kibble (Orijen) and the other a ~50/50 mix of almost entirely veg-free (veg are after minerals on ingredient list, so...) wet/frozen raw food. Miss kibble won't eat anything else, and the tiger's stomach seems to deal better with this food than anything else I've tried.
