Letting Your Dog Walk You
A poorly trained dog can pull you 
over while you’re out for a stroll. According to the CDC, tens of 
thousands of people end up in the ER every year because of pet-related 
falls. Many of these falls occur during walks -- either when a person 
trips over a dog or is pulled or pushed by one. Experts say obedience 
training is the best way to make sure your pooch doesn’t take you down 
during the morning walk.
Overlooking Ticks
After a walk in the woods, you check 
yourself for ticks, right? Don't forget about your dog. Tick bites put 
your dog at risk for Lyme disease, Rocky Mountain spotted fever, and a 
handful of other diseases. They can also cause serious illnesses in 
cats. If your pet has infected ticks, this puts the rest of the family 
at risk. If you find a tick, remove it carefully with tweezers, being 
careful to get all of the head and not to crush it. Ask the vet about 
tick control.
Ignoring Ringworm
If your pet has a round bald patch, 
ringworm could be to blame. Leave this fungus untreated, and you're 
putting your family at risk. People can get ringworm from dogs or cats 
by touching their skin or fur. Ringworm usually causes a reddish, 
ring-shaped rash on the skin or bald spots if it infects the scalp. If 
your pet has hair loss, take him to your vet to see if it could be 
ringworm.
Not Bothering to Deworm
Roundworms are common parasites in 
both dogs and cats. They cause diarrhea and vomiting and may lead to 
serious illness. But many people don't realize these worms are a threat 
to humans, too. An infected pet can contaminate soil or sand with tiny 
eggs. Kids may ingest the eggs by putting dirty fingers in their mouths.
 When the worms hatch inside people, they can cause blindness and other 
tissue damage. Ask your vet about regular deworming.
Skipping Flea Medicine
Skip your pets' flea medicine, and 
they aren't the only ones who will pay the price. Fleas will quickly set
 up shop on untreated pets, particularly in summer and fall, and fill 
your house with their eggs and young. Some people wind up covered in 
itchy sores.  Fleas can also transmit serious diseases to people 
including bubonic plague.  Ask your vet about long term flea medication 
and put a routine reminder on your calendar.
Not Spaying or Neutering Your Pet
Millions of cats and dogs 
live on the street or end up euthanized because of unwanted litters. 
Still, many people are reluctant to spay or neuter their pets. The fact 
is, spaying and neutering is a healthy choice for your pet. It reduces 
the risk of breast cancer in females and testicular cancer in males. 
Neutered males are also less likely to run away from home, mark their 
territory, or exhibit aggressive behaviors.
Keeping the Food Bowl Full
With the best intentions, some 
people keep their pets' food bowls full at all times. This is one of the
 most common mistakes pet owners make. The problem is that cats and dogs
 often eat more than they need. If food is constantly available, they 
will take in too many calories and put on too much weight. To avoid 
this, follow the suggestions on the pet food label or ask your vet for 
guidance.
Providing Too Little Exercise
Just like people, pets need 
exercise to stay healthy. Couch potato pets are prone to obesity, which 
raises their risk of respiratory problems and joint problems. The right 
amount of exercise for a dog depends on the breed and size, but vets 
recommend at least a half-hour each day. Taking brisk walks with your 
dog can help you get in shape, too.
Misreading Body Language
Sure, you love your dog. But do you 
really understand him? If you think a wagging tail is always a good 
sign, you could be in for a nasty surprise. When a dog wants to threaten
 someone, he may hold his tail high and wave it stiffly back and forth. 
Mistake this warning for a sign of playfulness and you could get bitten.
 To avoid misunderstandings, learn about your pet's body language.
Providing Too Little Attention
Just like children, your pets 
will get bored if you don't play with them. And boredom can lead to 
troublesome behaviors like chewing, digging, barking, and whining. Bored
 cats may resort to scratching and excessive meowing. Fight boredom by 
hiding treats for your pets to find around the house. Provide toys your 
cat can chase. Teach dogs to play fetch, tug-of-war, or hide-and-seek.
Not Socializing Young Pets
It's important to provide puppies 
and kittens with positive human interaction during their first seven 
weeks of life. This includes handling and play that fosters trust in 
people. Reputable breeders will begin this interaction, and you can 
continue the process when you bring your pet home. To develop a strong 
bond, play with your new puppy or kitten every day.
Leaving a Dog Alone Too Long
Spending 8-10 hours alone in a 
crate, tiny laundry closet, or even outdoors is too much for most dogs. 
It can lead to separation anxiety and destructive behaviors including 
chewing, soiling, digging, and nonstop barking or howling -- even 
depression in a timid dog. Better choices are doggie day care, a mid-day
 visit from a pet sitter, or a canine companion. Adult dogs can go 4-5 
hours in a crate but need exercise before and after.
Setting No Rules
Some people expect their pets to know right 
from wrong without being told. But human etiquette does not come 
naturally to dogs and cats. You need to make it clear that jumping up on
 people, scratching the furniture, and peeing on the carpet are 
unacceptable. Be consistent about the house rules, and reward your pets 
for good behavior. If you need guidance, consult a trainer promptly. 
Scolding Pets for "Accidents"
If you come home to find a 
puddle of pee on the floor, you may have the urge to yell at your pet. 
But animal behavior experts say this will do no good at all. The 
transgression took place in the past, and your dog or cat won't know why
 you are yelling. A better strategy is to praise your pets immediately 
when they do their business where they are supposed to.
Leaving Young Kids Unsupervised
Most children adore animals, 
but sometimes their enthusiasm can lead to someone getting hurt. Young 
kids may play too rough, pushing a dog or cat to strike out in 
self-defense. Be sure to supervise play time when a new pet joins the 
family. Set rules for how children should treat the pet and teach them 
to recognize the signs that a dog or cat wants to be left alone.
Letting Dogs Eat Spoiled Food
Your dog may be tempted to 
rifle through the neighbor's garbage in search of a treat, but don't let
 her! Food gone bad is no healthier for pets than it is for people. Dogs
 who eat garbage are at risk for bacterial food poisoning or irritation 
of the pancreas. Spoiled food may also contain toxic mold, which can 
cause vomiting, severe tremors, seizures, and death.  
Giving Bones to Dogs
We may think of bones as a wonderful 
treat for dogs, but the FDA paints a different picture. The agency warns
 that chewing on bones can injure the teeth, tongue, or mouth. Bones can
 also get stuck in the digestive tract, where they will have to be 
removed with surgery or an endoscope. If your dog likes to chew, ask 
your vet about safer alternatives.
Feeding Dogs Table Scraps
It
 can be hard to resist a dog that's begging at the table. You look into 
those big eyes and want to share your food with your pet. But rewarding 
your dog's barks or whines will only encourage more begging in the 
future. And then you can forget about quiet dinners with your family. If
 you want to share table scraps as an occasional treat, do it away from 
the table -- and use the food as a reward for good behavior. Also, some 
human foods can be toxic to pets.
Having No Disaster Plan
If an emergency forces you to 
evacuate your home, what will you do with your pets? Leaving them behind
 is not an option if your community is threatened by fire, flooding, or 
hurricane-force winds. And not all Red Cross shelters allow you to bring
 your pets. It's best to identify pet-friendly shelters and motels ahead
 of time, so you can keep your pets with you during an emergency.
