Online courses are all the rage. Here’s one from Udemy that caught our interest: Dog CPR, First Aid & Safety. Taught by Melanie Monteiro, author of The Safe Dog Handbook and a canine CPR and first-aid expert. Monteiro offers workshops and private consults in California and Oregon, and now, you can learn from her in the comfort of your own home. There are 36 lectures (three hours of video), covering pet CPR, canine Heimlich, how to stock a first-aid kit, how to take and read vital signs and more. Important techniques like how best to approach and capture an injured dog and restrain her for treatment, and how, why and when to use a muzzle (or not) are covered, using real dogs as subjects. Also included are tips on puppy-proofing your home as well as special pointers for dog walkers, sitters and pet-care providers. At only $60, it’s a great value. Learn more at udemy.com.
