Which of the following is NOT a sign of roundworms in animals?

Excessive barking is not a sign typically associated with roundworm infestations in animals. Roundworms primarily affect the gastrointestinal system, leading to symptoms such as diarrhea, a dull coat, and vomiting.

Diarrhea occurs as the worms compete for nutrients and can cause irritation in the intestines. A dull coat may result from malnutrition or the effects of parasite infestation, indicating that the animal is not absorbing the necessary nutrients effectively. Vomiting, too, is a common response as the body attempts to rid itself of the parasites that cause discomfort or pain.

In contrast, excessive barking is not linked to the physical effects of a roundworm infection. Barking may be a response to various other factors, including anxiety, excitement, or environmental stimuli, but it does not directly indicate the presence of roundworms in an animal. Understanding these symptoms helps in proper identification and treatment of parasitic infections in animals.
