Melanoma is a malignant tumour that originates from melanocytes. It has been reported in human beings as well many domesticated animal species (Reddy et al., 1998), and wild terrestrial marine animals. Melanomas are the most commonly diagnosed tumours oral cavity of canines (Goldschmidt, 1985; Faramade 2017). Gingiva common site for canine melanoma (OMM) but other parts like palatine, labile or...
We measured resting metabolic rate (RMR), daily energy expenditure (DEE) and metabolisable energy intake (MEI) in two breeds of dog during peak lactation to test whether litter size differences were a likely consequence of allometric variation in energetics. RMR of Labrador retrievers (30 kg, n=12) and miniature Schnauzers (6 kg, n=4) averaged 3437 and 1062 kJ/day, respectively. DEE of Labrador...
BACKGROUND Canine hip dysplasia (HD) is a common polygenic trait characterized by hip malformation that results in osteoarthritis (OA). The condition in dogs is very similar to developmental dysplasia of the human hip which also leads to OA. METHODOLOGY/PRINCIPAL FINDINGS A total of 721 dogs, including both an association and linkage population, were genotyped. The association population incl...
Copper is an essential trace element, but can become toxic when present in abundance. The severe effects of copper-metabolism imbalance are illustrated by the inherited disorders Wilson disease and Menkes disease. The Labrador retriever dog breed is a novel non-rodent model for copper-storage disorders carrying mutations in genes known to be involved in copper transport. Besides disease initiat...
The objective of this study was to evaluate body composition in small breeds of dogs as compared with larger breeds. Body composition by Dual Energy X-ray Absorptiometry (DEXA) was performed in 34 adult small and toy breed dogs. Results were compared with data obtained from 41 Beagles and 6 Labrador retrievers. Body weight, bone density, total calcium, fat grams, lean grams and bone mineral con...
In heterozygous females affected by an X-linked skin disorder, lesions often appear in a characteristic pattern, the so-called Blaschko's lines. We investigated a female Labrador Retriever and her crossbred daughter, which both showed similar clinical lesions that followed Blaschko's lines. The two male littermates of the affected daughter had died at birth, suggesting a monogenic X-chromosomal...
Standardised histological criteria are now available for the diagnosis of canine chronic hepatitis (CH). CH is common in dogs, but no studies have reported breed, age and gender distributions in the United Kingdom (UK). The objective of this study was to determine which breeds had an increased risk for developing CH in the UK and to report the age and gender distribution for those breeds. The d...
The deleterious effects of a disrupted copper metabolism are illustrated by hereditary diseases caused by mutations in the genes coding for the copper transporters ATP7A and ATP7B. Menkes disease, involving ATP7A, is a fatal neurodegenerative disorder of copper deficiency. Mutations in ATP7B lead to Wilson disease, which is characterized by a predominantly hepatic copper accumulation. The low i...
