My dog Bo, an 11-year-old Australian Cattle dog, was hyper and excited this morning but suddenly became lethargic when my sister visited. He usually loves to see her and was not excited about going outside. His appetite and stool have been normal, but he ate leftover eggs for breakfast and had a Christmas cookie and a new biscuit treat over the weekend. He has a lump on his chest/belly that the previous vet believes is full of fluid. What could be causing his sudden lethargy?
