Frequently Asked Questions (FAQs)

 

What kind of dog harness is best?

Before choosing the right dog harness, measure around your pup’s rib cage. And choose a size based on those measurements. The right fit is important because if the harness is too tight, this may be uncomfortable for them. If it's too big, they could slip out during walks.

Is it better to walk your dog with a collar or a harness?

The best way to know whether or not a dog harness is good for your pup is to talk to your veterinarian. They will instruct you on the best type and fit for your breed.

Is a dog harness a good idea?

The best way to know whether or not a dog harness is good for your pup is to talk to your veterinarian. Once you have decided on a type of harness for your pup, it may take a few days for your pup to adjust to a new dog harness, so watch carefully to ensure that they are comfortable.
