This week and next, we're pulling out some of the best "must know" information from our just- released books, "The Ultimate Dog Lover" and "The Ultimate Cat Lover." Each "must know" piece in the book has been developed with the help of one of the top experts in each area of expertise, and these experts are noted at the end of each tip. (This week, dogs. Next week, cats will get their due.)
Socializing
Once you have picked up your puppy at 8 weeks, you still have five weeks left of the critical socialization period.Your puppy needs to meet another 100 people in this period. If the puppy sees only family for the first months of life, he or she often will develop a fear of strangers.
Dr. Ian Dunbar, veterinarian and behaviorist, founder of the Association of Pet Dog Trainers (www.apdt.com)
Dog parks
Not all dogs learn to play nice, and some perfectly good dogs just aren't well-suited for the communal experience. Some will unintentionally provoke fights or fearfulness from other dogs with overly aggressive or unrelenting play. These are likely dogs who never learned to read the language of another dog's "leave me alone" cues and will keep pushing until there's a fight. Hormones can also play a role, and that's why it's usually best for dog-park play to be among spayed and neutered animals. Dr. Melissa Bain, veterinarian and behaviorist, head of Clinical Animal Behavior Service at the University of California, Davis, School of Veterinary Medicine
Low-shed pets
If you're looking specifically for a dog who won't shed much, get a small, long-haired dog and keep the coat trimmed short. Why? Because the hair of long-haired dogs falls out less frequently, and a smaller dog has less hair to shed than a larger one. If you keep the hair clipped short, the hair that does fall out will result in less volume to deal with. Dr. Craig Griffin, veterinary dermatologist, lecturer and instructor on skin problems in animals, and founder and co-owner of the Animal Dermatology Clinic
Canine cancer
The best treatment for cancer is prevention. Restrict your dog's daily intake of food to maintain a fit body weight, and feed him a balanced, delicious high-quality diet with limited amounts of carbohydrates (sugars), moderate amounts of good-quality proteins and higher levels of n-3 fatty acids such as DHA. Consider supplementing omega-3 fatty acids to potentially reduce the risk of developing cancer. Add regular exercise. Dr. Gregory Ogilvie, veterinarian and oncologist, former head of research at the Animal Cancer Center at Colorado State University, and director of the Angel Care Cancer Center
Trick training
All dogs can learn tricks. Which kind of trick depends on the dog his physical abilities and how quickly he thinks. Some breeds have a physical advantage: Basset hounds will never be as quick as border collies, for example. Even old dogs can learn new tricks, despite the saying to the contrary. In fact, old dogs love new tricks, because they enjoy the attention and fun of trick training. Liz Palika, certified dog-trainer for more than 25 years, award-winning author of more than 50 books, including "The Complete Idiot's Guide to Dog Tricks" (Alpha, $15)
That's just the tiniest of tastes of all the information that we've put into these new "Ultimate" pet books. Enjoy, and we'll be back with cat tips next week.
