My husband and I had just opened up a pet sitting business earlier that year.Our customers had slowly risen from three to thirty a month.We were busy through those hot summer months，driving between visits.Our services were strictly held at the pet owner's home.It was almost too busy for the two of us，but we were making good money!
We asked pet owners new to our services to phone two weeks ahead so we had enough time to meet the owners and pets at their homes and make any following meeting before the owner leaves.
One day，we decided to take on a new customer just two days before they would leave.We met the family，filled in a form，and spent some time with their dog，Hercules.He playfully jumped on us and touched our hands and arms using his tongue.The family laughed as he did this，showing us that he was very loving.
Two days later I appeared at the house，alone.I came up to Hercules and said hello happily.I filled up his water bowl and cleaned any messes he made.Meanwhile，he was so lovely sitting beside.I thought this would be the good picture to send to the owners，a usual service.After the light and “click” sound went off，Hercules rushed at me.I didn't know what had just happened until I noticed the drops of blood.I ran out and did the only thing—calling my husband.
