Fatigue And Tiredness
If your dog collapses, especially multiples times, that’s obviously a major cause for concern. Collapsing that is met with general fatigue, little or no interaction, and refusal to greet people is often a sign of cancer according to Jake Zaidel, DVM, of the Malta Animal Hospital in New York.
As a word of concern, even if your dog falls down and appears to be 100 percent the following day, a visit to a trusted veterinarian is still necessary. Your dog could be suffering from a hidden or silent medical issue that has yet to be addressed.
