Only way to get pass this is with time. My dog died last year had him for 11 years. I still think of him often and miss him dearly. It's weird I was way more sad about my dog dying than I was when some relatives died. Hang In there.
I'm assuming you weren't very close to those relatives. The bond you had with your dog is much more powerful than with somebody you see once a month or season. Emotions are more heavily tied to stronger bonds. People assume that humans are naturally supposed to care more about about other humans. Well, that's almost true. Humans only care for things that they
can easily care for. Centuries ago, animals weren't really reasonable things to care for. Don't worry about being more sad for your best friend than your relatives. It's more than alright.
