Which dog breeds are cited as having congenital lymphangiectasia?

• A. Yorkshire Terrier and Maltese
• B. Beagle and Labrador
• C. Poodle and Shih Tzu
• D. German Shepherd and Rottweiler

Answer: (A)

Congenital lymphangiectasia is a condition where the intestinal lymphatics are dilated from birth, leading to protein-losing enteropathy. It’s particularly a small-breed issue, and the breeds most frequently cited in veterinary literature for this congenital form are Yorkshire Terriers and Maltese. This makes those two breeds the best answer because they are the classic associations researchers and clinicians reference when describing congenital lymphangiectasia. The other breed pairs include larger breeds or less commonly implicated small breeds, so they are less typical matches for this congenital condition.
