Dogs develop resistance to Rhipicephalus sanguineus.

The capacity of Beagle dogs to develop resistance against infestation by adult females of Rhipicephalus sanguineus was investigated. The number of successive engorged females recovered from dogs at the second infestation of the tick was significantly less than at the first infestation. However, there were no significant differences in body weight, body length, body width of engorged females, feeding behavior, preoviposition periods or egg weight.
