If a Merle Aussie does have heath problems it’s likely to be hearing problems and blindness however this is much more common in ones that irresponsibly and Double Merle Aussies.

Responsible Breeding Practices

Breeders who want to produce merle puppies should mate a Merle Australian Shepherd with a non-Merle (m/m) Australian Shepherd as the incidence of health risks is reduced. Roughly 50% of their offspring will be Merles and most likely none will be Double Merles. That being said, there is still a risk of producing Double Merles as a cryptic merle mutation exists. Breeders should perform DNA tests for the cryptic merle mutation before breeding.

Double Merle Australian Shepherds

What Is A Double Merle Australian Shepherd?

A Double Merle (M/M) Australian Shepherd has little to no colour in their coat as they have inherited two copies of the dominant “M” allele. Unfortunately, Double Merle Australian Shepherds are affected by severe ocular defeats and deafness. They may be deaf in one or both ears and may be blind or have totally lost an eye.

Double Merle Australian Shepherds are also called ‘lethal whites’ due to their colouring and health issues. They are very controversial if they have been purposefully bred. Most official bodies refuse to register dogs that are a product of merle-to-merle breeding.

Double Merle Health Issues

Hearing Impairment – up to complete deafness
Vision Impairment – up to complete blindness
Skin Cancer – an increased risk due to the lack of pigmentation on skin
Micropthalmia – rare condition causing small and often non-functional eyeballs (high risk for Double Merles)

Shedding

Do Blue Merle Australian Shepherds Shed?

Australian Shepherds, regardless of their coat colour, are moderate to heavy shedders. They shed all year round and it is particularly heavy during moulting season. As Australian Shepherds have a double coat, the thickness of their undercoat will change depending on the season. It’s thicker during winter to keep them warm and thinner in summer to keep them cool. The transitional periods towards winter or summer are the two periods where shedding will be much heavier than normal.

If you are looking for a dog breed that doesn’t shed that much, a single coated breed is probably more suitable than a double coated one. Nearly all Poodle Mix breeds are classified as light to non-shedders so something like an Aussiedoodle, Groodle, Labradoodle or Bernedoodle would be suitable if you are still looking for a larger dog breed. If you love the temperament or look of an Australian Shepherd, an Aussiedoodle would be your best option as they are a cross between an Australian Shepherd and a Poodle.

Are Blue Merle Australian Shepherds Hypoallergenic?

Blue Merle Australian Shepherds are not hypoallergenic as they release a considerable amount of allergy inducing dander into their immediate environment. Dog allergy symptoms are usually caused by dander which is composed of tiny particles of skin shed by dogs along with a bit of their fur. It can be really problematic as dander is so small and can linger in air for long periods of time.

Allergy symptoms can also flare up from the proteins founds in dog saliva, urine and feces. Like dander, dried saliva can flake off a dog’s skin or fur and become airborne.
