Those weeks of careful monitoring have finally paid off — you're now the proud caretaker of a housebroken pup! But wait, is that a yellow stain partway up the drapes? And after you unclip Rex's leash in the dog run, and he maniacally bounds around for 45 minutes, it still takes a 10-minute game of "catch me if you can" to get him back on-leash to go home. What gives? Your puppy has grown into a teenager.
The Wide World of Spots
From the age of six to 18 months, your dog undergoes adolescence — that gawky stage between puppyhood and adulthood. Physically, your dog has his adult teeth, but he still needs to chew on hard toys. That cottony puppy coat is falling out during one tremendous shedding cycle, allowing the adult coat to grow in. He has almost reached his adult height, but for now is all loose elbows and gangly movement.
And what movement! During adolescence, the domestic canine resembles a perpetual-motion machine that requires superhuman stamina to wear out. It's a good idea to find your pup a friendly pack of other canine adolescents to run with in the safety of an urban dog run or suburban fenced-in yard. If your dog lacks canine friends, send him or her out with your resident human teen to fetch a Frisbee or go jogging.
