I put the collar on my dog a week ago and today there are 4 or 5 engorged ticks on his chest and legs (amazon.com)
That's right, not only were many (if not basically all) dinosaurs blanketed in feathers like jumbo roosters, but they also probably carried around pendulous clusters of engorged ticks. (gizmodo.com)
Engorged ticks typically are females preparing to lay eggs. (petsprinciple.com)
