I have had Frank since he was 4 weeks old. I rescued him. He knows basic commands and then a few. He is very sweet. He loves cats and dogs. He has been around children and he did not pay much attention to them. He is up-to-date with his puppy checkups and immunizations through All Creatures in Arlington. He has not been fixed yet. I was waiting until he was around 1 year old. The vet said the mastiff part of him takes longer to build testosterone. I need to give him to someone who has a yard he can run in. He goes to the dog parks and socializes with other dogs, I have to admit I do not have the ability to meet his needs. I have lots of toys, food, etc. that goes with him. This saddens me but Franks needs what is best for him. Please only serious inquiries. Text only please. Thanks
