Tollers are generally healthy. However, like almost all dog breeds, they have specific potential genetic disorders. Breeding stock should be tested for the following potential disorders:
- Hip Dysplasia - an abnormal formation of the hip socket that can lead to severe arthritis and lameness.
- Collie Eye Anomaly (CEA) - an inherited disease causing defects in the formation of the eye.
- Progressive Retinal Atrophy (PRA) - a group of diseases that cause the retina of the eye to degenerate slowly over time.
- Juvenile Addison's Disease (JADD) - a rare, early onset, chronic endocrine disorder in which the adrenal glands do not produce sufficient steroid hormones.
- Cleft Palate (CP1) - a birth defect whereby a hole in the roof of the mouth develops while the puppy is in utero.
