We live in a ranch community with 5 acres but not fully fenced. Our backyard is fully fenced with a 7’ fence. I have been pet sitting for my friends and neighbors since I graduated high school in 2010. At the moment we also raise chickens, I got into poultry about 3 years ago so now I have a backyard full of chickens. They are all in secure coops that dogs should not be able to get into, but I do ask that your dogs be ok with chickens. I never let them out when dogs are around but I also don’t want them tormented through the cages. As long as your pup is ok with them, they can run free in the backyard as much as they want. The remainder of our 5 acres is not secure, just the backyard. If your pup is not ok with the chickens then potty breaks will happen in the front yard on a leash. We also have 1 dog, a sweet pit/terrier mix. He loves everyone and has never shown aggression with any animal except cats. We babysit the neighbors miniature schnauzer regularly whom he gets along great with as well as big dogs. I lost my mastiff in July of 23’ and he did great with him as well, about 200lbs. He was a stray that showed up here and we kept him. So he does not play with toys or other dogs, he doesn’t seem to know how, he just likes to sleep on the couch or run in the yard. No issues with toy or ball or food aggression. At the moment, because of my chickens I am only taking smaller dogs, easier for me to manage if they do have issues with my birds. Big dogs would have to be checked around the birds first before they could stay. For the most part our dogs (personal and guest) have free run of the house. We usually put up a baby gate to keep them from going upstairs and in the carpeted family room, but the rest is free space. Crate trained is great, but not necessary. Whatever makes them comfortable.
