Eggs are excreted in the urine via the renal pelvis. These eggs are oval to cylindrical, yellow-brown, thick-walled, with a rough, knobbed surface, and 71-84 × 45-52 μm in size. [46] The eggs embryonate within two weeks to three months, depending on the ambient temperature, and then become infectious to intermediate hosts. [47]
Hapalonychia, is a condition in which a toenail or fingernail (or multiple nails) nail becomes soft and thin, causing it to easily bend or break. This can result from an inherited condition, [ 1 ] : 786 malnutrition , or debility.
Pathology is from both the adult worms, eggs and larvae. Cardio-respiratory signs are one clinical symptom. Chronic, coughing, exercise intolerance, dyspnea and tachypnea in young dogs is due to blood vessels being blocked by adults, eggs and larvae. The parasite also causes coagulopathies.
Signs include fever, vasculitis, and low blood counts. [6] Rocky Mountain spotted fever* is a rickettsial disease that occurs in dogs and humans.

Dogs with increased risk of infection: i.e. those used in sports, competitions, shows, or those kept in kennels can be given two treatments 4 weeks before and 2–4 weeks after the event. Professional dogs: i.e. therapy, rescue, or police dogs: 12 times a year, if excretion of worm eggs is to be excluded.
Early signs of infection in most dogs include limbular limping and anal itching. The eggs are oval or elliptical, measuring 60 by 40 μm, colorless, not bile stained, and with a thin transparent hyaline shell membrane. When released by the worm in the intestine, the egg contains an unsegmented ovum.
Eggs from T. vulpis are oval shaped with bipolar plugs and contain a thick outer shell. Their sizes range from 72–90 μm in length and 32–40 μm in width. [ 1 ] Because of their thick outer shell, T. vulpis eggs are very resistant to environmental extremes such as freezing or hot temperatures, thus allowing for their long viability in the ...
