Ralphie is a morning dog, meaning he is full of energy and ready to go when the sun comes up. At night, he likes to wind down and chill around the house. But if you are up and about, he will run and play at any time. He's smart, a good listener and understands the word No. He's crate and house trained and does not jump on the counter or furniture. Curiosity is strong in Ralphie, which is why he is an occasional fetcher (until he gets interested in something else). The combination of his love for the outdoors and his curiosity means he pulls on the leash, but he has improved his leash skills with some work and would be great with even more. He is social and gets along with every dog we've encountered (even those that don't seem so friendly) and has an easygoing nature that is great with guests (he has not been tested around cats or small children). In the house, he will follow you around all day long to keep you company. He currently does not like to ride in a car, but we are working with him on it. Ralphie is rarely vocal, except if he gets overly excited. Ralphie has moderate energy levels and would prefer a family or a house with a yard. He would also be a loyal companion to a single person or couple with an active lifestyle.
Puppies of all colours can potentially occur in the same litter. Colour is determined primarily by three genes. The first gene (the B locus) determines the density of the coat's eumelanin pigment granules, if that pigment is allowed: dense granules result in a black coat, sparse ones give a chocolate coat. The second (E) locus determines whether the eumelanin is produced at all. A dog with the recessive e allele will produce only phaeomelanin pigment and will be yellow regardless of its genotype at the B locus. The genes known about previously have had their number increased by the introduction of the K locus, where the dominant "black" allele KB is now known to reside. Black or chocolate Labradors therefore must have the KB allele. Yellow Labradors are determined at the E locus, so the K locus is irrelevant in determining their colour. Variations in numerous other genes control the subtler details of the coat's colouration, which in yellow Labradors varies from white to light gold to a fox red. Chocolate and black Labradors' noses will match the coat colour.
Outside North America and Western Europe, the Labrador arrived later. For example, the Russian Retriever Club traces the arrival of Labradors to the late 1960s, as household pets of diplomats and others in the foreign ministry. The establishment of the breed in the Commonwealth of Independent States (former USSR) was initially hindered by the relatively small numbers of Labradors and great distances involved, leading to difficulty establishing breedings and bloodlines; at the start of the 1980s, home-born dogs were still regularly supplemented by further imports from overseas. Difficulties such as these initially led to Labradors being tacitly cross-bred to other types of retriever. In the 1990s, improved access to overseas shows and bloodlines is said to have helped this situation become regularised.
Zanjeer ("Chain", or "Shackles"), a detection dog who detected arms and ammunition used in the 1993 Mumbai (Bombay) serial explosions. During his service, he helped recover 57 country-made bombs, 175 petrol bombs, 11 military grade armaments, 242 grenades and 600 detonators. His biggest contribution to the police force and the city was the detection of 3,329 kg of RDX. He also helped detect 18 Type 56 rifles and five 9mm pistols.
