My 4 yr old bitch refused her food tonight and didn't want to come out of her house. Her temp is on the high side of normal (102.6), she is hydrated, gums are red, CRT is immediate. Her stomach feels tight and seems to be a little painful to the touch. Shes inside now and ill watch her and if she doesn't improve ill take her to the vet in the morning . She just seems real listless. Anything I can do in the meantime?
