a extremely sad moment for me was when my puppy named buster died. I had 2 harlequin great danes from about their age of 2 months, at around a year, they were at my waist, I'm just over 6 feet. I didn't know the girl (Gabby) had gone into heat but apparently her brother(Gunther) did, I came home one day to find a small group of huddled together newborn crying puppies. Great Danes are so playful and gentle, most of the time anyway, mine were so playful, gunther thought that these must have been some kind of toys popping out of gabby as he started playing with them and chewing on them and what not.
after she was done, it seems gabby joined in the fun of tearing apart these new toys, there was puppy blood and guts all over the place, except a small group of 3 that stayed together(the afore mentioned group of crying puppies), it seems both dogs trampled 2 of the 3, so they died shortly after I found them. but 1, a surviver, like myself, stayed alive, the vet said he was fine and hadn't been stepped on or anything. I was so happy. he was gray with black spots, he was so cool, I spent lots of time with him and gabby to try to get her tyo mother him and feed him, but she was scared, and confused, and it was a week and a half later without any luck, she didn't want to, or was too young. so I had been feeding buster with a bottle and formula for puppies. he was doing so great, then one day, I came home, and he looked asleep, cause he loved sleeping, I waited a few minutes, then tried waking him, but he was dead. that was very sad for me.
