Boulder came to us as a foster dog at six weeks old. His owners wanted to use him as a guard dog for a construction storage yard when he got older. After raising him for six months, we knew he should never be a guard dog, so became ours. Now at 75 pounds, Boulder loves every human he comes in contact with and doesn't know he has become the gentle giant. Boulder is a mix of Irish Staffordshire Bull Terrier and Boxer.
