Plain-English summary
A group of 2-month-old beagle puppies was tested for protection against Canine parvovirus 2 (CPV-2), which can cause serious illness with symptoms like vomiting, diarrhea, and weight loss. The puppies were given either a special powder containing antibodies from chicken egg yolk or regular egg yolk after being exposed to the virus. The puppies that received the antibody powder showed no symptoms and gained weight, while those that received regular egg yolk had mild symptoms. This suggests that the egg yolk antibodies can help protect dogs from severe illness caused by CPV-2.

Abstract
The protective effect of immunoglobulins derived from chicken egg yolk (IgY) against infection by Canine parvovirus 2 (CPV-2) was evaluated in 10 beagle dogs orally challenged with a strain of the virus. The 2-mo-old dogs were divided into 3 groups and treated with powders containing CPV-2 IgY or normal egg yolk for 7 d after the challenge. The 4 dogs receiving normal egg yolk (control group) demonstrated mild symptoms typical of CPV-2 infection, such as vomiting, diarrhea, and weight loss. No symptoms were observed by 16 d after challenge in the 3 dogs receiving 2 g of IgY powder. Of the 3 dogs receiving 0.5 g of IgY powder, 2 had clinical CPV-2 disease; however, the manifestations were less severe than in the control group. Furthermore, the IgY-treated groups had significantly greater weight gain and shorter duration of virus shedding than the control group. These results indicate that IgY is useful in protecting dogs from CPV-2-induced clinical disease.
