Hyper mode...

Question
QUESTION: After Echo (my 8 month old cairn puppy) comes in from a walk or is just really hyper, he starts going crazy, running around the house and especially biting my dad's slippers... Today he put his hand down and Echo bit him and he started bleeding... I put him down on his back and stuff and said no but is there any other way to stop this?

ANSWER: DO NOT force a dog onto its back for any reason; this is not the way to obtain dominance or to correct behavior.  First, the dog has no idea why you're doing this (unless correction occurs within ten seconds of the behavior, the dog does not connect it) and second, it confuses and frightens the dog and erodes any trust the dog has in you.

At eight months of age, the dog's brain is undergoing physiological changes and this can also be a fear phase.  Your dog is behaving normally when he "races around the house" and redirects his excitement toward slippers; in this dog's case, his over excitement seems a bit over the top.  It's most likely that the dog did NOT perceive the object as your dad's hand, since his aggression toward the hand was so sudden and given without warning.  He must have misperceived the hand in that split second.  Normally, active aggression proceeds slowly: growling, snapping, "soft" bite, harder bite, breaking skin, etc., over time.  This dog's cognition clearly misfired (or backfired) when he was caught in this emotional frenzy and merely redirected his frantic state to a hand, rather than a slipper (REMEMBER, dad's scent is on the slipper, dad's hand...)

You need to keep this dog on lead for about ten minutes following his return from outdoors.  In fact, trading his outdoor leash for a house lead (long, lightweight nylon leash) is a good idea: make him "sit" for the exchange of leads (without coercion, use positive reinforcement training to teach him to "sit" VOLUNTARILY), this will help to calm him.  If he begins to go ballistic around the house randomly (and this is also seen in dogs this age), merely CALMLY step on the leash and pick it up; hold onto the dog until he is calmer without speaking to him, touching him, etc.  This restraint will help him collect himself and remember where he is.

Use the positive reinforcement training to slowly teach this very smart breed some obedience work, slowly and in short sessions, over the next few weeks.  it will enhance his cognitive ability, promote you psychologically, give him a way to please you for reward, and enhance his trust in you.  If, after a few weeks of this training and leash restraint, his behavior has NOT changed, repost.

QUESTION: Thanks for that info :]

By the way, how can I correct him being crazy outdoors because when someone came up to him to pet him he jumped up to his hand and nipped... he was off leash.

Answer
There's no reason for your dog to be off leash in a public place when he is clearly not trained in any manner and has NO RECALL.  This is a recipe for disaster.  Dogs "nip" out of excitement and anxiety (their jaws click together if they are very over excited) and a dog that has been played with in a rough way by its owners has learned it's ok to use teeth on people.  Terriers are tough little dogs and require a very strong hand with positive reinforcement training and clear signals of leadership (NOT coercion, NO punishment, NO "dominance" routines).  Your dog appears to be EXTREMELY anxious.  You need counseling and help in person, not in print.  Find a certified applied animal behaviorist ASAP and help this dog before he develops serious unwanted behaviors.
