My in laws have a fantastic dog. She is a 14 year old husky mix who basically sleeps for 23 hours a day and begs for food the other hour. Chelsea is a lovely dog but spoiled a bit rotten. She's always eaten like a bird, sometimes her food will sit for an entire day before she finally eats it in the middle of the night.
But Monday she didnt eat, or Tuesday. Or Wednesday except for some scrambled eggs and hashbrowns. Then Friday she started to strain to defecate. Then Saturday she had a normal poop. Then yesterday she started vomiting and had blood around her tail.
So my in-laws are taking her to the vet today (it's a holiday here) to figure out what's wrong. My differential diagnoses were (best case scenario) an anal gland abcess causing discomfort and inappetance which is then causing tue vomiting. Or pancreatitis, low grade and chronic but exacerbated by the eggs and hash browns. Or some kind of tumor that's bleeding. (worst case scenario).
I'm taking the boys for a hike today, close to where they live, so I'm going to stop in and see what the vet says.
She is a great old dog and my in-laws have done geriatric work ups on her every year for the past three. Her blood has always been normal excePt for some mildly elevated liver levels. She's always been a very healthy dog so this has my MIL very worried.
