A friend recently forwarded me this column about grieving the loss of a dog.

It’s so true that losing a dog can be harder than losing a human family member, as friends and relatives who’ve recently lost dogs (recently = in our lifetime) can confirm. I still miss my Jana, after a year and a half.

Why is this so hard to bear? As the column-writer notes, dogs are more intimately part of our lives than most of our human friends and even relatives. Other than a longtime spouse, your dog is probably the person (yes, dogs are persons …) who has spent the most time with you, seen you at your best and worst, and who knows you best. I’d argue that dogs know us better than any human can, since they can read so much more of our body language and, in most cases, read our minds!

They’re also great company. Sure, Cali sulks when I won’t share my dinner and huffs and stalks off when I pick up my phone. But she — and most dogs — offer largely uncritical companionship. They’re easy to be with, comforting when you’re having a hard time, and always up for some fun. They never, ever try to talk you out of a late-night ice cream binge, for example — or, to be fair, a long hike.

While non-pet people may never understand why the loss of a pet is so hard, pet people should know that there are many, many people who do understand. And who also know that even when, as many of us do, we get a new dog, we’ll never fill the hole left by the ones we’ve lost.

This column is dedicated to Hannah and Ziggy, my sister’s dogs (pictured with Cali, Jana, and Alberta) who passed away in February.
