- CEA (collie eye anomaly): genetic abnormality affecting the eyes, which may not create any kind of problem in certain cases, lead to a vision impairment in others or in the worst case complete blindness.
- MDR1 (Multi Drug Reactivity 1): is a gene that, under normal conditions, encodes a particular protein (P-glycoprotein) that eliminates unwanted substances from cells (and from the central nervous system). In case of anomalies, this protein does not work, it follows an accumulation of toxic substances. Dogs with this type of pathology are hypersensitive to some active ingredients that are usually found in products against fleas and similar, anesthetics and medicine.
HD (Hip Dysplasia): radiography of hip dysplasia. To be performed approximately at 1 year old (or later).
Must be done at an early age within 8 weeks old. It must then be repeated in adults, especially in case of reproduction. The visit in early age is very important as with the growth the eye completes the development and the pigmentation therefore as adults could “hide” pathologies that are instead clearly visible at few weeks of life. The visit must be carried out by a veterinary specialist in ophthalmology who issues a certificate with European significance.
There are other checks that can be performed: genetic tests for DM, VWD3, CNGA1-PRA in addition to the elbow radiography (ED elbow dysplasia) and the check of patella luxation (PL patella)
Warning!!In Italy, none of these checks / exams is a must to do a litter of sheltie and unfortunately bad breeder can also breed due brother/sister or match wrong colour like sable x blue merle.
Each breeder independently chooses if and what to test according to their own ethics.
In 2015 I created this group on Facebook for all italian sheltie lovers
the aim of the group is to learn aout the breed, share informations, photos and videos.
