Got a nice Brittany puppy last year. The dog is about 7 months old now. At first she chewed everything in sight and peed if you even looked at her. She has grown out of the peeing but she has become a hyperactive, chewing, digging, jump all over-you monster. She spends about half of the day outside and has over a dozen acres to run around. She finds anything left outside or on a porch and destroys it. She's ripped up flower pots, drain pipes, child's toys, boots, boxes, brooms, shovel handles, and even CHEWED UP a porcelain mug that was accidentally left where she could get it. She chases any and every sort of wildlife including deer and this trait, along with a love of tearing up flower beds, has gotten so out of hand that my wife would be very, very pleased if the dog went away. I have never seen a dog so hyper. Any suggestions short of Ritalin?
