The solution to that is for them to build a dog park. Dogs can and will get plenty of exercise, even at a walk, provided that the owner takes them. If they don't have as much time, put a doggie backpack on them, put a little weight in it, and it adds to the amount of exercise that the dog gets. If someone puts in a dog park, they then have a place to run free with other dogs, plenty of space and "dog friends" to play with.. and there's no excuse for the owners. Owners need to have the responsibility to *any* animal, and to those around them or other animals around them as much as possible that the animal they own/provide for comes into contact with. I mean, honestly, it's a pain in the butt sometimes, but, you know, you sort of sign on for that when you get an animal.
Take for example.. if you live in a farm area, where there's tons of space, it's not as bad for neighbors, etc, if an animal runs. Neighbors are a.) likely to be animal friendly, because they're likely to have a farm of their own and b.) not close to your house, which means less likelihood that they'll see said animal.
If you live in a townhouse community, where you effectively have no "land" of your own, you're right on top of your neighbors, all the land is "community" property, the responsibility is much different. You have to then also take responsibility for a dog that barks, which means, don't let your dog sit outside for hours and hours and barks because it's unhappy... i.e. set your inside up so that the dog can't do whatever it is you're preventing him from doing by putting him outside.. make sure it's well-trained and or on a leash, make sure that you pick up any doggie land mines when it potties.. it's a different set of responsibilities.
Now, don't get me wrong, I think it's up to each individual on how they decide to take care of their animal, and that depends, I'm sure, at least partially on how their neighbors are, and where they live and how they're brought up.. also this depends on the animals.
What I've said above is my personal opinion, and it's how I've kept my animals. That may not be right for everyone. I may not think that one person's method is right, but honestly, that's just my opinion. My dogs have always lived indoors, stayed indoors free roam while I'm at work, were well trained, and only ever went outside to potty, or for a walk or car ride or something. They never sat outside, fenced yard or no. That's just how we've always had our dogs. And from their standpoint, at least, they didn't want to be out running free, and given the option 99% of the time, would pick coming indoors with the family. (there were occasions when we had a runner that would inspire the other two to get a wild hair up their butts and go running off through the countryside, and also my keshond who thought it was great fun, and was impossible to catch when he broke free, but he was a nutjob). Now I definitely try not to let my cats roam free. Mostly because I fear for their safety, and the safety of the neighborhood teeny fourfooters. I don't want a dead pile of squirrels, bunnies, mice, rats, and other various wildlife brought to me daily. I very seriously doubt that I'd let them out even if I lived in an area where they had plenty of space and were safe from cars and annoying the neighbors. *edit* I forgot to add the disclaimer that Elisa, our last dog, Great Dane, was the exception to the above. We didn't get her as a puppy, she wasn't well-behaved, and couldn't be walked due to her many, various issues, including her insane aggression.
Anyway, the point here originally, long before I got off track.. was dogs will go after the sea turtles, and .. aren't they endangered?? I'm fairly certain even if they aren't now, they at one point used to be endangered. Those owners have a responsibility to their animals to get off their butts and exercise their dogs instead of putting other wildlife at risk because they feel it's okay to let them run free instead of taking them for a real walk. Laziness is no excuse to get rid of leash laws, imo. That being said, it is a pain in the buttocks to have a dog and have to exercise them daily. It's one of the reasons that I like cats better... they may be high maintanence, but not that kind of maintanence.
All righty, then, that's my Saturday morning novel.
