How we write health guides
We're dog owners, not vets
Our health guides help you understand what's going on and what your options are. They don't replace a vet exam, and we never pretend otherwise.
More about our team →- Facts come from primary sources such as the AVMA, the Veterinary Oral Health Council and peer-reviewed studies, linked at the end of every guide.
- Every guide has a "when to call your vet" section.
- We tell you what a product's evidence does and doesn't show, even when we earn a commission on it.
Common dog health questions
How often should I clean my dog's teeth?
Daily brushing is best, and brushing several times a week can still be effective, according to the AVMA. Wipes and food powders help dogs who won't accept a brush. Keep a yearly dental check with your vet either way.
Why is my older dog losing muscle in the back legs?
Age-related muscle loss (sarcopenia) usually shows in the hind legs first. Conditions like arthritis, kidney disease or diabetes can make it worse, so have your vet rule those out.
Are dog health supplements worth buying?
Some have real evidence and many don't. Look for published, placebo-controlled studies or, for dental products, the VOHC Seal of Acceptance. Check with your vet first if your dog takes medication.
When should I call the vet instead of reading online?
Any sudden change: not eating, trouble breathing, collapse, bleeding, repeated vomiting, or pain. Online guides are for understanding, not for emergencies.
