i am so upset. i had a 4 month old maltipoo, Rocky...my mom came and picked him up last saturday to keep him while we went on vacation, and she called me sunday and told me that he died. the vet said he went into a diabetic coma. she said he was playing too hard (my mom has a puppy too and they loved to play together) and got too excited, i guess didnt get enough food and water and collapsed. has anyone ever heard of this? i hadnt, but i guess its one of those freak things. but i really didnt miss him too much on vacation, because he wasnt supposed to be there, but now that we are back i am so upset cause he's supposed to be here happy and playing!
