Ancestors of the Cao da Sera de Aires were used for herding livestock in the Serra de Aires and Alentejo, Portugal. This herding dog is native to Portugal and throughout the 20th Century he was kept as a working dog.
Known also as the Portuguese Sheepdog, Portuguese Shepherd Dog or Serra de Aires Mountain Dog, there are some questions surrounding the breed's ancestry as there are few records of dogs before 1900. The dog is thought to be related to the Pyrenean and Catalan Sheepdogs and that it has descended from Briards which were imported into Portugal and crossed with the Pyrenean Sheepdog.
The Cão da Serra de Aires breed standard was accepted by the Portuguese Kennel Club, and the breed was recognized internationally in 1996. The dog was also recognized by the United Kennel Club in the Herding Group in 2006.
The Biewer is, or was, a piebald Yorkie caused by a recessive gene in a breeding of two Yorkshire Terriers. On Jan 20, 1984 a piebald Yorkshire puppy was born in Hunsruck, Germany to Gertrud and Werner Biewer. The puppy was considered beautiful and the Biewer’s fell in love with it and began a process od selective breeding in an effort to breed piebald Yorkies. Based on a friend’s suggestion, they named this group of puppies, “Biewer Yorkshire Terrier a la Pom Pon”. By 1989 the Allgemeiner Club der Hundefreunde Deurschland (ACH) officially recognized the Biewer Yorkie as a separate breed. Today they are recognized world wide as two separate breeds.
Today there have been genetic studies done that have declared the Biewer Terrier to be a separate and distinct breed from the Yorkshire Terrier, not simply tricolored Yorkies. The BTCA (Biewer Terrier Club of America) changed the name and standard to an original one for the Biewer Terrier. Mrs. Biewer has accepted and signed this revised standard and it is the only one she has accepted. This new standard allows the Biewer Terrier to have a black coat and an undocked tail. In 2014 with the new standard the American Kennel Club Foundation Stock Service (ACK/FSS) accepted the Biewer Terrier. Some breeders still want the breed called the Biewer Yorkshire a la Pom Pon, but Mrs. Biewer has objected to this, insisting the dog is a terrier. The Biewer Breed Club of America (BBCA) insists on the breeding of Biewers only to other Biewers. This is opposed by others who are importing Biewers and breeding them with Yorkies. The result is not recognized as a purebred dog. BBCA breeders do not engage in this type of cross breeding or condone them. The BBCA breeds only dogs that meet the standard set by the BTCA.
The first two Biewers were imported to the States in 2003 by Donna Hall. They made history in 2003, when they were accepted by the IABCA (International All Breed Canine Association) and entered their first dog show. Today they are shown in rare breed dog shows around the world. Today there are two standards in operation for the Biewer as the American Biewer and the North American Kennel Club continue to follow the German standard while the BBCA follow the revised standard approved by Mrs. Biewer.

Being forewarned , you can get your pet to the vet quickly before the illness gets out of hand.
There are some pet owners who want to have their pets tested by the Orthopedic Foundation for Animals as well as the Canine Eye Registration Foundation to rule out health defects such as hip dysplasia and cataracts before they manifest themselves in their pets. This is of particular importance to breeders so as to prevent the parent dogs passing bad genetic conditions to the puppies.
This is a common skeletal disease where the dog’s hip joints don’t develop properly. It can be terribly painful for your pet to get around. It’s a genetic condition and while it is more prevalent in big dogs, any breeds are susceptible.
Your dog will battle along with painful joints and sometimes his hind-end will be lame. You’ll notice that once lying down, he battles to get up again. Fortunately vets are well acquainted with this ailment and they have different options to treat and manage it.
Cataracts in your dog come about from a disease process which affects the lens of the eye. The eye loses its transparency and impairs vision. There are some instances where cataracts can cause blindness. You’ll see a whitish gray area in your pets eye. The most common cause of cataracts is genetics. Get your pet to the vet who will do certain tests to evaluate the eyes and make a recommendation.

You have to be careful about cleaning your pet ears if you don’t know how, as it could damage the ears. Your vet can always advise you on how this is done.
As previously mentioned the Biewer Terrier has a very sensitive stomach and intestinal system. He should be fed low protein dry dog food. Watch for signs of food allergies such as scratching or chewing on his feet. Feed 2-3 times a day but the Biewer Terrier is one of the few dogs that you can safely free feed unless you notice substantial gaining of weight.
Health issues are few as mentioned previously. However, make sure your Briewer’s ears are free of debris and wax, make sure their teeth are brushed and they show no signs of allergies. Along with liver shunts, sensitive intestinal and stomach issues and floating patellas, these are the other minor issues that might occur. Watch for diarrhea and off colored stools.
