Notes:
Died due to severe heart failure only three days before her third birthday. Her sire is known to descend from lines of dogs producing heart failure. He has several half siblings out of the same dam who, like Muffins, have died at a very young age. I would advise anyone against ever using this sire or males out of the same dam as him. Watching your best friend suffer and finally die from a horrible disease like this is a nightmare I do not wish on my worst enemy. And for the future of this breed we need to weed out the bad genes from the good ones. The dam of Muffins has whelped three litters from three different non-related males. Only one litter produced this heart defect. Therefor there is no reason to suspect the dam lines to be responsible for this defect. It can only come from the dam side of this sire.
