Pet care advice travels fast, and some of it is wrong. Here are common myths and what to know instead.
Myth: One dog year equals seven human years
Aging varies by size and breed. Dogs mature quickly in the first couple of years, then age at different rates. Large breeds tend to age sooner than small ones.
Myth: Indoor cats don't need vaccines or vet visits
Indoor cats can still be exposed to viruses, escape or need boarding. Core vaccines and regular exams matter.
Myth: A dog's mouth is cleaner than a human's
Dogs carry plenty of bacteria, and bites and licks can cause infections. Dental care is still essential.
Myth: Cats always land on their feet
Cats can right themselves in a fall, but falls from heights still cause serious injuries. Secure windows and balconies.
Myth: Pets eating grass means they're sick
Many healthy dogs graze. If grass-eating comes with vomiting or lethargy, ask a vet.
Myth: Table scraps are harmless
Some foods, such as grapes, onions and anything with xylitol, are toxic. Fatty scraps can cause pancreatitis.
Myth: Grain-free means healthier
Most pets don't need grain-free diets, and some have been investigated in connection with heart disease. Ask your vet.
Myth: Spaying or neutering automatically makes pets fat
Metabolism can change, but weight gain comes from calories in and out. Adjust portions and keep your pet active.
Myth: Dry food cleans teeth
Kibble doesn't replace brushing or professional dental care.
Myth: Pets will let you know when they're sick
Many hide pain. Small changes in appetite, behavior or habits often mean something. Regular exams help, and so does a quick check-in. Chat with a licensed vet on Waggle Vet any time something seems off, and find a nearby veterinarian for routine care. Keep records in your pet health vault.
