We adopted him at over seven years old from a shelter, already somewhat affected by hip dysplasia and arthritis; he had an amazing, sweet personality and aristocratic looks. How nobody adopted him for the 18 months he was in the shelter I can't imagine, but that was our great fortune.
We had more than 5-1/2 wonderful years with him; he slowed down but the only real problem he had was with stairs; we walked every day, he inhaled his food with joy, and the special bacon and Culver's French Fry treats were like giving mana to a starving person; he radiated joy like no other dog. And with very few exceptions (hyper, naughty kids who abused him) he made friends with _everyone_ he met.
He was diagnosed with cancer in March; it had metastacized by the time we found it, but they thought it might be treatable with low-intensity chemo (not to cure, just to stop or slow the growth and give him more quality time). But he also came down with a digestive problem that we had to clear up before he could start chemo. That took over a month; he was due to start chemo this Tuesday, and had been feeling, walking, doing better every day for the past week...
After a normal morning Saturday, he was sleeping and had a horrible attack, with vomiting, and then (we later found) aspirated some of the vomit. After that he had trouble breathing, and became mostly unresponsive. Though he had shown no earlier signs, the emergency vet said he had serious pneumonia, and might have suffered a mild stroke, and that subsequent attacks at the ER had the same result (aspirating vomit). The odds for his recovering to a state of comfort, or decent quality of life were vanishingly low. The tumor on his lung had grown during the time we couldn't give him chemo and even with an oxygen feed his blood oxygenation was low... When we left the ER on Saturday, though, he was once again responding, recognizing us, and trying so hard to get up and follow us out...
He didn't really respond to us when we went to the ER today. But when we left to make the final arrangements he tried to follow us again... he knew it was us and he wanted to be with us.
He died in our arms, his whole dirt-side Pack present and mourning.
He walks with his elder Packmates now, making friends with passing souls and angels.
Damn it all. We thought we had at least weeks, months if we were lucky, of good time with him left. Now in less than a day, he's gone. And we're broken...
Don't take your pups for granted.
