I have many years of experience with presa canario and cattle dogs. The dogs would be staying in the front yard, which is fenced in. On our walks, we would walk around with the goats and other animals, on our way to the back pasture, where the dogs would be free to run around in the open field. I do ask that all dogs are up to date on flea medicine and dewormed, since this would be a new environment for alot of the dogs, and these would be new animals alot of them have never been around, its always best to be on the safe side to make sure everyone is ok. I also have a nikon camera, so I can take pictures of the pups on our walks or of them with the goats. P.s- if you know your dog is high prey drive, please let me know before hand, so I dont let them in with the goats lol they can still play with them and play on the farm, just not be in the pen with them.
