I'm so very sorry that you lost your sweet Clover, especially to such a horrible tragedy. Of course our dogs are family, people who say they are 'just dogs' have never been blessed to have one of these amazine animals in their lives so of course they cannot possibly understand.
Give your daughter a hug from me, each of my sons took a very long time to get over it whenever we lots a pet, from hermit crabs to a much beloved boxer. It's brutal for them I know, but love and devotion brings grief that often takes quite a while to get over. Please give her all the time she needs and let her know that whatever time frame she needs is okay.
We're all thinking of you, please come here to talk anytime and know that we understand.
