Myth No. 6: An excited dog is happy to see you.
"It's very easy to come home to a dog that is jumping, running around, or spinning in circles, and interpret that as the dog being glad you're home. But that's not what's really happening," says Cesar Millan, dog behaviorist and star of the TV series Dog Whisperer.
It's a sign that your dog has more energy than he can handle in that moment.
Millan's advice: Ignore him when he's overexcited, then reward him with attention when he calms down.
Myth No. 7: A dog urinates on the rug because he's mad at you.
It's not about anger.
"Often there is an underlying medical problem, like urinary stones or an infection," says veterinarian Roy Kraemer, DVM.
It could also be stress, anxiety, or a territorial issue. Whatever you do, don't respond with anger. That only makes things worse.
Myth No. 8: Female dogs should have one litter before being spayed.
If you're worried your dog will feel empty if she never becomes a mother, don't. That's a human emotion, Kraemer says. It's healthier for your pet not to wait before being spayed.
"Female dogs' chances of developing breast cancer and life-threatening uterine infections are greatly reduced by spaying prior to their first heat cycle," Hunter says.
Myth No. 9: Dog parks are totally safe and healthy.
Dog parks can be great fun, but there can be some risks. Parasites like fleas, ticks, and worms, and viruses like parvo and protozoa, can lurk in contaminated water and dog stool.
If your dog gets in a fight, that can also mean wounds and injuries. But, Kraemer says, most problems can be avoided by using common sense and paying attention to what's going on around you.
