The Glen of Imaal Terrier () is a breed of dog of the terrier category and one of four Irish terrier breeds.
 It is sometimes called the Irish Glen of Imaal Terrier or the Wicklow Terrier, and the name of the breed is often shortened by fanciers to just Glen.
Ca de Bou or Perro de Presa Mallorquin is a medium-to-large sized molossian-type breed of dog, with a strong, powerful, elongated build.
 The difference between the sexes is in the head, the circumference is greater in dogs than in bitches.
 The Perro de Presa Mallorquin was almost extinct after World War II, and the few remaining dogs were crossed with Majorca Shepherd Dog, Bulldog and perhaps Alano Espanol.
 While extant specimens are all crossbred, the population as a whole retains standardized breed recognition in two kennel clubs, Fédération Cynologique Internationale, and United Kennel Club (using the FCI standard).
The Majorca Shepherd Dog (Catalan: "Ca de bestiar" , Spanish: "Perro de pastor mallorquín" ) is a domesticated breed of dog, used in the Balearic Islands of Spain, both for guarding sheep and as a general purpose farm dog.
 It is a medium-sized dog with black fur or black with white markings on its chest.
 It comes in both shorthaired and longhaired varieties.
"Panda German Shepherds" is a term coined for German Shepherd Dogs that exhibit a rare genetic mutation that causes white spotting the traditionally non-white marked breed of German Shepherd Dogs.
 This frequently debated color is often dismissed as a result of crossbreeding.
 However, new research has proven insightful of the true origin of this new marking.
The East European Shepherd (VEO) (in Russian: Восточно-европейская овчарка (ВЕО)) —is a breed of dog that was developed in the 1930-1950s based on German Shepherd Dogs to create a larger cold-resistant breed for military use, police work and border guard duties in the Soviet Union.
 VEOs are also used as guide dogs for the blind and there are VEO therapy dogs.
 This breed is popular in Russia where it entered a public culture and acquired a legendary status as an extremely smart and loyal dog devoted to their owners.
 The breed is well known in other ex-Soviet Union republics.
 In the West, the East-European Shepherd is a rare breed that is not well known: information about the breed on online sources, in English, is limited and often incorrect or distorted.
Schutzhund (German for "protection dog") is a dog sport that was developed in Germany in the early 1900s as a breed suitability test for the German Shepherd breed.
 The test would determine if the dog displayed the appropriate traits and characteristics of a proper working German Shepherd.
 Today, it is used as a sport where many breeds other than German Shepherd Dogs can compete, but it is such a demanding test that few dogs can pass.
The Caucasian Shepherd Dog (Adyghe: Хьэпарий, "Khʹèparij", Адыгэ Мэлыхъуэхьэ, "Adygè Mèlykhʺuèkhʹè" ; Karachay-Balkar: Басхан Парий, "Baskhan Parij" ; Armenian: Կովկասյան հովվաշուն, "Kovkasyan hovvašun" ; Azerbaijani: "Qafqaz çoban iti" ; Georgian: კავკასიური ნაგაზი, "Kavkasiuri nagazi" ; Turkish: "Kafkas Çoban Köpeği" ; Ossetian: Аргъонахъ, "Arghonaq" ; Russian: Кавказская овчарка, "Kavkazskaya ovčarka" ) is a large breed of dog that is popular in Russia, Armenia, Azerbaijan, and Georgia.
 It is extremely popular in Georgia, which has always been the principal region of penetration of Caucasian shepherd dogs.
 The official standard of this breed is fundamentally based on the dogs taken from Georgia.
Rare breed (dog) is any breed of dog that is small in number and is used to refer to both old established breeds such as the Stabyhoun and Glen of Imaal Terrier or newer creations.
 Since dogs have greater genetic variability than other domesticated animals the number of possible breeds is vast with new crosses constantly occurring, from these both selected and random crosses may come new breeds should offspring reliably breed true to type.
 New breeds from the wild such as the Carolina Dog are quite rare compared to attempts at breed creation from man as found in the American Hairless Terrier which sought to exploit a mutation.
Masticatory muscle myositis (MMM) is an inflammatory disease in dogs affecting the muscles of mastication (chewing).
 It is also known as atrophic myositis or eosinophilic myositis.
 MMM is the most common inflammatory myopathy in dogs.
 The disease mainly affects large breed dogs.
 German Shepherd Dogs and Cavalier King Charles Spaniels may be predisposed.
 There is a similar disease of the eye muscles found in Golden Retrievers. Symptoms of acute MMM include swelling of the jaw muscles, drooling, and pain on opening the mouth.
 Ophthalmic signs may include third eyelid protrusion, red eyes, and exophthalmos (protruding eyeballs).
 In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus).
 The affected muscles include the temporalis, masseter, and pterygoid muscles.
 The disease is usually bilateral.
The old German herding dogs (German: "altdeutsche Hütehunde" ), including old German sheep-dogs or old German shepherd dogs (altdeutsche Schäferhunde ) are a group of traditional types of working, herding dogs from Germany.
 They are landraces consisting of working strains of dog, and some of them are the types from which the modern German Shepherd Dog was developed as a standardised breed.
 The landraces are not recognised by the Fédération Cynologique Internationale but some have their own standards, which are for working ability not appearance traits.
