Detailed explanation-1: -Ticks are parasites that attach themselves to animals and people, feed on blood, and transmit diseases directly into the host’s system. The disease occurs when an infected tick bites a dog or a human and transmits the disease into the victim’s body.

Detailed explanation-2: -Ticks are obligate parasites of vertebrates, to which they attach themselves for varying periods of time, and are well-adapted to this mode of transport.

Detailed explanation-3: -The type of interaction between ticks and dogs is parasitism. Here ticks are ectoparasites, i.e., parasite feeding on the external surface of the host. In this type of interaction only one species is benefitted.
