Brushes that are handy for grooming Aussies

The Pin Brush is probably the primary brush I use on an adult coated Aussie -
I like a small slicker brush, that isn’t as harsh, like a Four Paws Tender Touch mini, as I mainly use it for their ears and legs and feet -
A brush with Boar Bristles is great as a finishing brush, getting surface things off of it, as well as on younger Aussies that don’t really have the adult double coat yet -
I really like the Terrier Palm brush for starting dogs out on, to get them used to being brushed -
here is the same basic one but with a rubber back so can use for bathing if want -

Genetics & Health

Who doesn’t want a healthy best friend…one who remains active long into old age? Sadly hereditary diseases are on the rise in all breeds. A growing number of dogs are dying before even reaching old age or reaching old age but with chronic health problems. Understanding the genetics and potential health issues affecting this wonderful breed is a good first step in halting this upward trend (ASCA).

Aussies and many other herding breeds can be sensitive to certain drugs - Washington State University has developed a simple testing kit to screen for the mutant MDR 1 gene. For more information please go to their website:

The Double Merle

A 'double merle' is exactly that - a puppy who's both parents have a merle coat pattern (not just Aussies, doesn't matter whether blue or red) - when 2 merles are bred together they have a 1 in 4 chance (25%) of producing a double merle pup (or homozygous merle), and these pups have a high probability of having hearing and/or vision impairment. These pups usually have what is called 'excessive white coloration', meaning they have much more white than the breed standard allows, particularly around their eyes and/or their ears. Their impairment can range from slight to severe, meaning only one ear has some hearing loss to minimal hearing in both ears, from some vision loss in one eye to neither eye is fully formed and totally blind.

Australian Shepherd Personality and Character

(This article was written by Kathleen Cole and is reprinted with the author's permission)
The Australian Shepherd was developed to be a moderately sized, intelligent, all-purpose stock dog of great character and endurance. Many Aussies today still do the work they were bred for, and even those that have never seen sheep or cattle usually have a strong herding instinct. This means that Aussies need fenced yards and leashes, as the temptation to herd dogs, children, and traffic can simply overwhelm them.

Being bred to work hard all day means that most Aussies are not content to be couch potatoes, although Aussies have individual characters and some are more sedate and quiet- natured than others. For the most part, however, these are high-energy dogs who need a purpose in their lives, a job as it were. Owners must be committed to give their dogs the time and attention they require through play and training, for as with any dog undirected energy can turn towards destructive behaviors such as digging and chewing. Running, jumping, and rough-housing are all a part of being a normal Aussie.

The great intelligence of these dogs, necessary to out-think and control livestock, can be detrimental when left untrained and unused. Aussies are quite capable of out-thinking their owners. Obedience training is highly recommended as a means of teaching owners how to channel the typical Aussie's innate desire to please into appropriate behaviors. Aussies learn very quickly, so be certain you are willing to keep your Aussie occupied with walks, play, and training to benefit both mind and body.

Although many Aussies are friendly with everyone, the Australian Shepherd as a breed tends to be somewhat reserved and cautious around strangers. With Aussies of this nature owners should encourage the dog to meet people but not force encounters. Aussies are often quite protective of their family and property, a desirable trait in some situations but not acceptable in others, and some dogs never accept strangers. As with all dogs, poorly socialized Aussies may become aggressive without proper training.

Aussies are generally healthy dogs, and can be expected to live up to twelve years or more, so ownership can be a lengthy commitment. Although minimal, there is some grooming required to keep the coat clean and conditioned, such as regular brushing and nail trimming. To maintain their high energy levels, typical active Aussies may eat more than other, more sedate dogs of similar size, so be prepared to feed plenty of high quality food.

However, Aussies are perfect for people wishing to own a highly trainable, versatile, super-smart dog that can work/play "till the cows come home". If you have the time and commitment for an Aussie you won't be disappointed. These special dogs deserve special owners. Their loyalty, drive, character and whimsical sense of humor place them in a class by themselves!
