Abstract

Dogs presenting with polydipsia, polyuria, polyphagia or weight loss are seen relatively commonly in clinical practice. There are multiple causes for each of these problems, and it is important that the clinician formulates a complete list of differential diagnoses prior to undertaking diagnostic investigations. This chapter considers polydipsia and polyuria, polyphagia, inappetence and weight loss. Quick Reference Guide: Testing for hyperadrenocorticism: some important considerations.

Ultrasonograms of the bilaterally enlarged (a) left and (b) right adrenal glands in a dog with PDHAC. Note that the shape of the glands is bilaterally preserved; however, both glands appear ‘plump’. Asterisks indicate the long axis of the gland. Reproduced from the BSAVA Manual of Canine and Feline Ultrasonography.
