Spider bite

JMO but spider bites are worse then snake bites. I have never had necrosis set in on a snake bite but had a lab in the kennel that got bit on the muzzle one time. I knew it was not a snake. Anyway his muzzle swelled up and I put him on antibiotics. Two days later I had to take him to the vet. About a silver dollar size spot was rotting out & it took a long time to heal with a lot of scar tissue. I was pretty sure it was a black widow because anytime you turned a dog house over at that place it was full of them.
Twenty years or so ago, my wife got bit by a brown recluse sitting on the steps. She spent 4 days in the hospital & she ended up with a golf ball size indentation on the back of her leg after it healed.
