And where do you go when you need information on potty training, behavioral issues and more? Again, there’s a lot of general information available online, but not all sites offer accurate information. The Internet is a wonderful tool for pet parents for these and many more reasons.

It’s our responsibility to ensure we use only those sites that provide science-based, truthful information.

Search for reputable sites online can be an exercise in frustration, so we’ve done the research and created a list of the best sites that provide the best health and medical information for your pet. Let’s get started!
