Now it’s time to worry about Farley. In all honesty, if a dog eats a spider (even if it is a poisonous one) it won’t cause a problem. The problem from spiders occurs when the spider bites and invenomates the dog. The venom in the dog can cause irritation and necrosis.
If this venom is ingested as it would from Farley eating the spider without being bitten (which is what it looks like in the cartoon), it gets diluted out and broken down in the dog’s stomach and doesn’t cause any problems.
