Shaping the future
of animal health

Why is my dog behaving strangely?

You want your dog to be happy, but his behavior suggests something else. Maybe he’s acting unusually nervous or skittish. Loud sounds may cause him to tremble. A simple walk around the block could leave him panting and salivating. Or maybe you have an older dog that seems disoriented, or is having accidents around the house.

A dog that is experiencing frequent fear, anxiety, phobia or brain aging may be suffering. If intervention is delayed, the problem can become worse. The earlier behavioral problems are identified the better.

Below are Virbac-developed products for to enhance behavior in dogs. Talk to your veterinarian if you have any questions about these products. As with any product you use on your pet, always listen to your veterinarian’s instructions and read the product label.
