They bark, they lick and sometimes they drive us crazy. But we love them anyway.
More than 46 million people in the United State have at least one dog and every now and then, some of their behavior can be puzzling -- some normal, some not.
Anna Ball Hodge, who lives in Raleigh, says her 9-year-old pug Stella, attacks her whenever she tries to leave.
"I have scratches on the back side of my legs," Hodge pointed out. "It's bad. It draws blood. I mean, you're going somewhere and your leg is bleeding."
Dr. Heather Moeser, of Downtown Mobile Vet is Stella's veterinarian and says her behavior is not normal because it happens every day rather than occasionally.
"It's more of a dominance thing," Moeser explained.
Hodge said another thing to watch out for is "sometimes she'll start spinning and we can't quite figure out what it is."
"They're doing this because their anal glands are a little bit full, and they can be uncomfortable," Moeser said.
For Adam Page and Patrick Lackey, their 13-year-old dog Ami is terrified of thunderstorms, has a lot of anxiety and is putting on weight.
"The thunderstorm phobia is common in some pets," Moeser said. "They can have such anxiety that some pets will jump through windows, pets that will eat a couch, and many times in those instances, they'll need medication."
Moeser recommends that owners find a safe place for dogs to go to, and let them stay there. She doesn't recommend holding them when they're frightened because it will just reinforce their fear.
Moeser says that if the behavior or problem persists to consult a vet or a trainer.
