Pedigree Breeds

The breed is large and heavy-boned with great physical strength, but is still agile enough to perform the all-purpose farm duties it was originally used for. Its breed standard calls for a black, white, and rust colored coat. The Greater Swiss Mountain Dog is sociable, active, calm, and dignified, and loves being part of the family. It is relatively healthy for its size and tends to have far fewer problems than more popular breeds in its size range. Among the four Sennenhunde, or Swiss mountain dogs, this breed is considered the oldest, and is also the largest.

Welsh Corgis have historically been used as herding dogs, specifically for cattle. They are of the type of herding dog referred to as "heelers", meaning that they would nip at the heels of the larger animals to keep them on the move. Both Pembrokeshire and Cardigan are historically agricultural areas of Wales.

The two Corgi breeds are named for those regions. Once interbred, the Kennel Club designated the different types as two distinct breeds in 1934. Slightly smaller than the Cardigan, not quite as long in body and with a smaller ear and straighter front legs, the Pembroke was traditionally docked, but that differentiation no longer exists since the docking ban. However some breeders have worked hard to produce natural bobtails. The Pembroke has always been the more popular breed, perhaps helped by the Royal patronage it has received since the reign of King George VI and carried on by our present monarch Queen Elizabeth II.

The American Akita is a large, powerful working dog. The dogs are very intelligent, extremely loyal, and can sometimes show an "aggressive" streak, almost exclusively towards dogs of the same sex. American Akitas are not aggressive towards people, but have a highly developed guard and protection instinct. American Akitas also have a strong hunting instinct and may regard small animals as prey to be hunted. Some do not show signs of affection towards people who are not members of their family or people they see regularly.
The American Akita is not hyperactive and adapts to a sedentary life, but it is important for his health that he exercises regularly.
