'Dog Star Daily Declares January Shelter Dog Prevention Month
Dr. Ian Dunbar's AFTER You Get Your Puppy should be required reading for anyone who is thinking of raising a puppy. That's why we are offering it here for a limited time as a free download during "Puppy Season" – the month of January.
Most shelter dogs were once perfectly normal puppies exhibiting typical, though often undesirable, puppy behavior.
House soiling, nipping, growling, resource guarding, destructive chewing, excessive barking, hyperactivity, jumping- up, leash-pulling and general unruliness are reported as primary reasons why people surrender their dogs to shelters or let them stray (to be captured and taken to shelters).
The presence of these same behaviors is also a major reason why people do not want to adopt shelter dogs. Yet these typical puppy behaviors are so easy to channel or eliminate with the right tools and information.
AFTER You Get Your Puppy covers the last three developmental deadlines that your puppy needs to meet before he is six months old. Skills that will keep dogs out of shelters and in their original homes:
The most urgent priority — Socializing Your Puppy to People
The most important priority — Teaching Bite Inhibition
The most enjoyable priority —Continuing Socialization in The World at Large
