When thinking about insects that can cause health problems in dogs and cats, common ectoparasites like flea or ticks usually come to mind. These are often easily identified because fleas like to live on their furry hosts, and ticks remain attached to their hosts for several days while feeding.
Flea and ticks are parasitic insects that require hosts to complete their life cycle. In contrast, spiders are not parasitic, meaning that they don’t require a dog or cat host to life out their lives. Most spiders would very much like to hide away from other animals, but there may be situations when a spider bite occurs.
Almost all species of spider inject venom into their bites, but the amount of venom that is injected is very small. For black widow spiders, however, even the tiniest amount of venom can cause serious health problems. What happens when a dog gets bitten by a black widow spider, and what can you do about it?
