Artem Dog crossed the rainbow bridge a few days ago. He'd been off his feed for a few weeks, but the vet could not find anything wrong. He suddenly started breathing (not panting) ~ 70 times a minute. We went straight to the doggie ER. After a long wait, it turned out he had gone into acute cardiac failure. They tried to diurese him to reduce pulmonary edema, but it seemed his mitral valve had completely failed. He died in only a few hours.
Mrs Artem is miserable when we don't have a dog, so we got Artem Pup only a few days later. Between still deeply mourning an excellent dog and trying to get used to having a new puppy underfoot who bites everything, and is still a bit young for much training, emotions at La Casa del Artem are largely mixed, confusing, and running high.
I do hope time heals all wounds.
