Abby's dog is showing symptoms such as slow growth and loss of hair. Her dog is suffering from which type of disease? A. Contagious B. Parasitic C. Chronic D. Deficiency

B :Parasitic

Explanation:

One of the very common cause of hair loss in dogs is an infestation by parasites like mites, fleas or lice. Most frequently, if a dog is losing hair around its neck,body and tail, there’s a high chance it’s due to fleas. These little tiny parasites can rapidly infest the dog and irritate their skin; this can cause intense scratching, which in turn can cause hair losses in the dog

Abby's dog is definitely suffering from a DEFICIENCY type of disease.

Therefore, option (D) is correct.

Symptoms, such as hair loss and slow growth can occur when living organisms lacks the recommended amounts of vitamin D.
