Solid fence all the way around is what I would do and some type of gate at the front ( I don’t like gates ) but get an enclosure around the area that you can control .
We are big dog people have pits/ pit mixes. All dogs that originally started off with a home somewhere else , not wanted lost , whatever the case…
I call in welfare checks regularly when driving any park if the dog looks questionable, 9 times out of town, the agency is familiar with the park. Talked to animal control officers on this topic, know rescues, locally.
Found dogs almost dead, brought back to life, found dogs almost hit by cars then hit by a car, then we did a leg amputate dog has a loving family in Maryland now.
I think a lot on this topic, I don’t know the answer. But talking with animal control , often times, the people who get their dog taken / lost will just end up with a perpetual cycle and get another animal. Different mindset, more of a disposable commodity…
One thing we are doing now , we found a dog, possibly a breed dog, in a very poor part of town, we are investing time and money in trying to educate the person on proper animal care. We took the dog for a vet visit, explaining heartworm to the owner, how to care for it etc. etc. I only watched a couple episodes of it but Pitbull and Paroles seem to try to “educate” the people in the community when they moved over to NOLA.
Fundamentally, and will vary greatly as this issue is not in all parts of the country. There is an oversupply of animals, no really barrier to getting them ongoing care. The problem perpetuates with reproduction so now instead of worrying about 1 dog, you have 6 dogs ,then 36 dogs…
More in depth than is required here but I would def keep in mind that even if you no longer have these dogs, more can come into the picture with time.
Maybe you are on to something with the electric fence. I personally don’t like anything that could hazard our residents seems like some level of liability je barb wire.
I would also go over and talk with them. Not in the manner of keep your dogs on your side but hi, I have this place Im trying to run respectably we have had complaints , I understand you want your dogs to roam free. Any chance we might be able to work together and accomplish a common goal? Would It help for me to build you a dog run for these guys? And get you a pizza delivered every month to show my appreciation for you helping me out.
Then at the same time you can work to see if long term, you can get any department or regulation to start to work on managing something like this. Cities might have something like a leash law to regulate roaming dogs.
But at the end of the day , I think the answer is embedded in care and education . Maybe not the immediate answer , quickest or cheapest, but education and care.
