Black widow spiders – these spiders are very common. They are mostly found outdoors or in crawlspaces outside the house. Their webs are usually very disorganized and resemble cotton candy. They are not too aggressive and bites happen one they are inadvertently bothered.
It can be very difficult to diagnose a spider bite from any type of spider. Generally, the bite is more painful and over time the area around the bite starts to look angrier and there can be varying amount of tissue damage.
In small breed dogs and sensitive dogs, the systemic signs can be quite serious with signs of severe pain ..and changes in the heart and respiratory system..treatment is supportive.
