Toxoplasma gondii is an apicomplexan protozoan parasite that infects a broad range of hosts, including dogs. Due to the high rate of dogs naturally infected with T. gondii and its correlation with immunosuppressive diseases, attention should be paid to the occurrence of this parasite in canine population, especially puppies, which are considered of high risk for developing the disease. Toxoplasmosis in puppies is particularly important, because the effects of the disease may have consequences on animals’ lives, and they may have immeasurable value, being considered as family members. The main objective of this chapter will be to discuss important aspects involving congenital toxoplasmosis in this animal species.
