The popular thing, for a long time has been for NO animals to be in public parks or on public beaches. People just didn't clean up after their pets, there were instances of kids getting bit, etc., etc., etc.
Now, slowly, slowly, they are starting to open up these "dog parks." the two parks near me state that NO kids will be allowed in the "dog park." But, on Saturday, kids over 14, with supervision, can come in.
Dogs play patterns and instincts are different from ours. All it is going to take, is for ONE little kid to get seriously hurt at one of these "dog Parks," and they will all close up, and we can go back to having no place to bring our animals.
Snoop and Dottie run so fast and hard at our park, that if a toddler were to unexpectdly get in their path,....well, I shudder to think about it. Right next to the "Dog Park" is the "Children's Park," with swings and toys and with a double fence between the two areas, so no little fingers can get nibbled on.
I have 15 grandchildren, ranging from newborn to 14 years old. (Two sets of twins in there, too.) Our dogs are socialized with our kids. The babies are presented to the dogs, who start out by being allowed to lick their feet. I would never let my GRANDKIDS, who the dogs KNOW, be left alone in a room together with my dogs, without an adult! And I trust my dogs!! But, better to err on the side of caution.
Dogs are NOT allowed in the fenced in kiddie play yards, or on the tennis courts, etc., and little kids have no business in the "DOG PARK," where they could be possibly at the mercy of strange dogs, with all of them being off leash, and could risk getting hurt. Again, being safe than sorry.
Anyway, just wanted to vent my opinion. I love kids AND animals too much to see anything happen to any of them.
