Glad the 'ji pups didn't tangle with that bastard. My dad has had two dogs bit by rattlers out on the hobby farm. Both survived, one barely though.
They were blissfully unaware.
Do you know what the wound looked like? When I was out there over memorial day weekend I let the mutts out to run around when I was unloading the car. Milo came back limping and wouldn't put any weight on one of her front paws the whole weekend which was kind of swollen.
I thought she had just sprained an ankle or something, no outwards signs of being sick, just lazy/lethargic. When I got back to KC this wound popped up so I took her to the vet and there were like "Dunno but here are some antibiotics and anti inflammatory meds"
The only thing I can think of was she got bit by some sort of snake but they didn't pump her full of venom.
