As a dog groomer and pet owner, I highly recommend taking a Pet First Aid course. I have certified in Pet First Aid several times, and now hold a American Red Cross Pet First Aid certificate. I have rarely had to use the skills I learned, but I have been grateful for the training when I needed it. For example, two of my dogs have choked, and required immediate assistance or they would no longer be with us. A neighbour’s dog was hit by a car and was badly injured.
A Pet First Aid course can take anywhere from 4 to 12 hours, usually on a weekend. A Google search for your city will yield class providers and dates. Groomers can also usually attend certification classes at most of the major trade shows. It is a small amount of time to spend on something that could have a profound result for your family. Ask your pet caregivers, the sitters, walkers, trainers and groomers, if they have taken a Pet First Aid course.
I have also purchased a terrific resource for home and travel. It is an app for your phone or tablet that contains nearly all of the information you would need in a pet emergency and includes excellent videos on how to perform the techniques. For the minimal cost of $3.00 you can have your reference textbook on hand at all times. Find it at: http://jive.me/apps/petfirstaid/
