I myself had a little Cavalier King Charles for 8 years, unfortunatly, he was killed by a german shepherd while walking in the street.
Of course, i was devastated as well by that loss,i just couldn't withstand the silence in my house after he died, so i eventually bought a new puppy.
It helped a lot, raising a new little pup', both for me and my family.
Here's the little buddy now (pic attached)
My only wish is to give him a good and happy life, and i wish all dog owners wished the same (not everytime the case unfortunatly)
