Of course he went straight for the dirt pile and mud.
Yesterday I took Mico to the vet for his puppy visit and vaccinations. Poor guy! It was such an ordea for him but he did a lot better than I thought he would.
We are still convinced he is part pirahna but it is getting better. We ignore the bad behaviour and put him in his big kennell with no toys for about a minute for time out. The first night the kennell door was like a revolving door. Last night was much better and today was even better, not perfect but he is coming along. Thanks for the suggestions and encouragement. It helps knowing I am not the only one with a dog that has puppy rage.
