You’ve probably heard it before: Cats and babies don’t mix. A wagging tail means a friendly dog. But are these so-called nuggets of wisdom really true? Here’s what the experts have to say about these 10 commonly believed myths about our pets.

Myth: Cats always land on their feet.

Fact: While it is true that cats instinctively control their fall and have an uncanny ability to land feet first, this is not always the case. Cats can be injured during a fall and they should not be ‘tested’ or allowed to climb in high places.

Myth: A wagging tail means a friendly dog.

Fact: Not always! Tail wags can mean different things, some friendly and others not. Instead you need to look at the overall posture of the dog and anything else it’s doing. Relaxed dogs generally have a gently wagging tail held horizontally or slightly lowered, and a raised tail usually indicates the dog is feeling confident. A dog with its tail tucked can indicate anxiety, avoidance or caution. Signs that you should back off from a dog include a stiffly lowered tail (wagging or not) combined with a lowered head, direct stare, closed mouth, and ears held back.

Myth: Animals that are neutered or spayed gain weight.

Fact: Not true. As with humans, your pet’s weight is typically related to food intake and exercise. An animal’s diet should be adjusted throughout its life to take into account age, activity and lifestyle.

Myth: Cats can’t be taught to walk on leash.

Fact: Dog-lovers aren’t the only ones who can enjoy a stroll with their furry companions. Yes, most cats can be easily trained to walk on a leash. Just be sure to keep your cat clear of temptations such as trees that it may climb and get tangled in.

Myth: If a dog’s nose is cold, it is healthy.

Fact: A dog’s nose is usually cold because of the evaporation of the moisture put there by the dog’s licking. A dog could have any number of illnesses and still have a cold nose.

Myth: ‘People food’ is bad for your pet.

Fact: This is sometimes true. Certain foods such as chocolate, grapes, garlic and onions can be toxic for your pet. (Read more on foods you should never give your pet.) You should also avoid giving your pet food that is spicy or high in fat. However, some foods such as carrots, apples, crunchy or lightly steamed vegetables and meat with the fat and gristle trimmed off are fine to share. If you are feeding your pet ‘people food’ on a regular basis make sure you use high quality ingredients and provide a balanced and complete diet. (See Cooking for your pet.) Note: Keep in mind that feeding your dog or a cat from the table even once can create a determined beggar.

Myth: With dogs, bad breath pretty much comes with the territory.

Fact: While unpleasant breath can be normal, really bad breath can be a sign of dental problems. Ask your vet to look at your dog’s teeth regularly and follow a dental plan.

Myth: Your cat is a danger to your baby.
