Abstract

Our understanding of canine coat colour genetics and the associated health implications is developing rapidly. To date, there are 15 genes with known roles in canine coat colour phenotypes. Many coat phenotypes result from complex and/or epistatic genetic interactions among variants within and between loci, some of which remain unidentified. Some genes involved in canine pigmentation have been linked to aural, visual and neurological impairments. Consequently, coat pigmentation in the domestic dog retains considerable ethical and economic interest. In this paper we discuss coat colour phenotypes in the domestic dog, the genes and variants responsible for these phenotypes and any proven coat colour-associated health effects.

Top Tips for Managing Home and Kennel Infestations With Brown Dog Ticks
Thorough cleaning of the environment to remove tick biomass followed by premise treatment by an experienced exterminator can hasten elimination of ticks. Brown dog ticks are long-lived off the host and may continue to emerge from the structure for many months; a long-term approach is needed to eliminate the population.
Lightning deaths in three outdoor dogs: A case study.
The three dogs were found close to each other, under a truck with a series of damages, such as burning of the tyres, the electrical control unit, and the trailer's ABS control unit.
Common Neurologic Diseases in Geriatric Dogs.
Neurological diseases are common in geriatric dogs, and although they can present with dramatic clinical signs, in a high percentage of cases, adequate management and a good quality of life for the patient can be achieved with symptomatic treatment.
Performing an Avian Physical Examination in Practice
As with mammalian physical examinations, it is important to develop a consistent order for the avian examination to thoroughly evaluate each body system. Some components of the physical examination differ between avian species. For example, cloacal palpation is performed in chickens, but not in parrots.
Canine distemper outbreak and laryngeal paralysis in captive tigers (Panthera tigris).
All suspected and confirmed cases of CDV infections were significantly associated with laryngeal inflammation, which developed into paralysis in almost 50% of cases. Altogether, 50% of all tiger cases with chronic infection developed stridor at 314 days after virus infection. Therefore, laryngeal paralysis may result from CDV infection and degeneration, potentially affecting the peripheral and central nervous systems. This condition could pose a life-threatening risk to tigers.
