In Puerto Rico I have since their were puppies 2 Rottweilers and 1 Scottish Terrier. I teach them how to sit, lay down and give me their leg to a low five. All of that my dogs can do it by signs. My dog respect me when they are eating I can take their food out. I talk english and spanish. I love dogs, I have the patient with the dogs, If your dog is agressive I can take away that from him. I teach my dogs to pee in the pads. I can try to teach your dog whatever you want I can find the way to your dog do what you want. If you want it can be by signs. Thank you. a
