Poodle visible swelling. A dog with GDV requires immediate veterinary care. The dog's survival usually depends on whether the owner can get to a veterinarian in time. GDV risk is increased with faster eating and a raised feeding bowl. Breed size is correlated with litter size and Standard Poodles have the highest litter size followed by Medium, Miniature, and Toy. Toy Poodles have one of the smallest litter size of all breeds. The stillborn rate and early neonatal mortality (death within 1 week from birth) in poodles are lower than the average across all breeds. Poodles are crossed with other breeds
Dog breed the other European dogs despite reports of direct Scandinavian origins dating back 5,000 years. The dog which accompanied the ancestors of Native Americans from Siberia is extinct. The spread of modern dog breeds has been difficult to resolve because many are the products of the controlled breeding practices of the Victorian era (1830–1900). In 2010, a study looked at 48,000 Single nucleotide polymorphisms that gave a genome-wide coverage of 912 dogs representing 85 breeds. The study found distinct genetic clusters within modern dogs that largely corresponded to phenotype or function. These included spitz-breeds, toy dogs, spaniels, Mastiff-like breeds, small terriers,
