I took my puppy from a dog foster home about a year ago. I love him to bits; he has a great personality, and I feel that he loves our family so much. BUT, whenever I leave him at home he pees in the house: on the carpet, on the bed, on flowers.. My husband and I were thinking about taking him to 'doggy school', but then again, it’s extremely expensive, and the nearest 'doggy school' is far away from us. Maybe you have some advice? THANK YOU!!!!
