I haven't found anything on here so am wondering if anyone has had a dog be too hot?  This was one of the first symptoms she started with (way before limping).  It would be in the middle of the night where she'd get up and go to the middle of our bedroom floor and loudly flop onto the floor like she was so hot she was going to pass out.  It was a very dramatic-actress-type move.  Then we'd notice how when she'd normally lay outside in the sun for hours, that she'd only do a few minutes before wanting to come in.  She's still doing this now, several months later and after amputation.  This weekend, one evening she was laying on the couch sprawled out (laying this way is a fairly new position for her too) and her body felt like an oven, it was so hot to touch.  The vet has had us take her temperature a few times at home (when it was still undiagnosed as cancer) and it was on the warm side, but never a really high fever.  She was diagnosed with a bacterial infection a couple months ago, but that has since cleared from the antibiotics, so it shouldn't be from that, but it also doesn't seem to be related to cancer either?
