What Are the Symptoms of Ticks on Dogs?

Ticks are small obligated ectoparasites that feed by sucking the blood of their hosts. Hosts of these species can be dogs, cats, birds, humans and sometimes some amphibians as well. They live and flourish in warm and humid environments.

Their life cycle is usually divided into four stages, egg, larva, nymph and adult. Ixodid or the hard ticks generally take one year to become adults from eggs and have three hosts in its lifetime. Agrasid or the soft ticks, on the other hand, take about seven nymph stages (also known as Instars) to become a complete adult. Each of these stages requires meal in the form of the food, for reaching the next instar. This blood feeding behavior of ticks makes them the carrier of different organisms which can cause more than twelve diseases in dogs and humans alike.

Some of the most debilitating species of ticks are found in tropical countries. Tropical bont ticks have especially racked havoc in African and Caribbean countries.

Ticks are arachnids and are most active during the spring season. They hide in tall grasses and look for a chance to climb on the body of your dog.

Some of the common symptoms are irritation and redness at the point of infestation, inflammation, excessive stretching and trauma. However, some of the species of the tick have adapted to suppress or negate the host’s response on its infection; therefore, most of the bites are usually, painless.

Nevertheless, over the period of time, the symptoms become quite serious, like systemic illness from the infections, hypersensitivity reactions. At times, the saliva of females tick release a toxin in the blood of dogs while feeding, this toxin is responsible for tick paralysis. Other times, excessive blood consumption by the ticks can lead to a deficiency of blood in their body, which is commonly known as Anemia.
