Differential gene expression analysis in French bulldog high grade oligodendroglioma: breed-associated differences in tumor and tumor microenvironment gene expression

Several canine breeds, including boxers, Boston terriers, and French bulldogs, belong to the same phylogenetic clade and have a higher risk for high-grade oligodendroglioma (HGO) than the general canine population. Despite their shared increased risk for HGO, French bulldogs treated with immunotherapy have experienced worse survival outcomes compared to boxers and Boston terriers...

Modern pedigree dogs in the United Kingdom Kennel Club: a journey through shifting population landscapes and demography

The limited genetic diversity in pedigree dog populations and the associated increased burden of inherited disease have led to calls for the development and implementation of effective population management strategies.

Cellular localization of a variant RAPGEF5 protein associated with idiopathic epilepsy risk in the Belgian shepherd

The Wnt signaling pathway is critical for normal embryonic development. Disruptions in the Wnt signaling pathway have been linked to neurological disorders. The RAPGEF5 protein is a partner in Wnt signaling and a RAPGEF5 3-bp insertion is associated with increased risk for idiopathic epilepsy in the Belgian shepherd dog. The 3-bp insertion risk variant introduces an alanine...

Awareness, experiences, and opinions by owners, breeders, show judges, and veterinarians on canine Brachycephalic Obstructive Airway Syndrome (BOAS)

Exaggerated brachycephalic features have been highlighted over the last decade by their profound effect on the health and welfare of the affected dogs. The term brachycephalic obstructive airway syndrome (BOAS) was launched in the early 2000s and has received worldwide attention and awareness. At the same time, the popularity of brachycephalic dogs increased. This study aimed to...

Shih Tzus are a popular dog breed in the UK although there is relatively little reported information on their health. This study aimed to characterise the demography, common disorders and mortality of Shih Tzus under primary veterinary care during 2016 in the UK using de-identified clinical records from the VetCompass™ Programme. The study population of 336,865 dogs under...

English Cocker Spaniels under primary veterinary care in the UK: disorder predispositions and protections

The English Cocker Spaniel (ECS) is one of the most popular dog breeds in the UK but information on disorder predisposition and protection is limited. Using anonymised veterinary clinical data from the VetCompass™ Programme, this study aimed to compare disorder predisposition and protection between the ECS and the remaining dogs under primary veterinary care in the UK during 2016...

Is it now time to iron out the wrinkles? Health of Shar Pei dogs under primary veterinary care in the UK

The Shar Pei is a common dog breed with a distinctive appearance caused by hyaluronosis that has been linked with several health conditions. Anonymised primary-care veterinary clinical records were explored to extract data on the demography, common disorders and mortality of Shar Pei in the UK in 2013. The study population of 455,557 dogs included 1913 (0.42%) Shar Pei. The mean...

Resequencing of the TMF-1 (TATA Element Modulatory Factor) regulated protein (TRNP1) gene in domestic and wild canids

Cortical folding is related to the functional organization of the brain. The TMF-1 regulated protein (TRNP1) regulates the expansion and folding of the mammalian cerebral cortex, a process that may have been accelerated by the domestication of dogs. The objectives of this study were to sequence the TRNP1 gene in dogs and related canid species, provide evidence of its expression...

Genomic analysis and prediction of genomic values for distichiasis in Staffordshire bull terriers

Distichiasis is a condition characterized by aberrant hairs along the eyelid margins. The symptoms are usually mild but can lead to ulcerations and lesions of the cornea in severe cases. It is the most frequently noted ocular disorder in Norwegian Staffordshire bull terriers (SBT), with a prevalence above 18% in the adult population. A complex inheritance is assumed, but there is...

Dog breeds and conformations predisposed to osteosarcoma in the UK: a VetCompass study

Osteosarcoma is a malignant bone neoplasia that has high welfare consequences for affected dogs.

Cataracts in Havanese: genome wide association study reveals two loci associated with posterior polar cataract

Cataract is considered an important health issue in Havanese, and studies indicate a breed predisposition. Possible consequences of cataracts include lens induced uveitis, reduced eyesight, and blindness in severe cases. Reducing the prevalence of cataracts could therefore improve health and welfare significantly. The most frequently diagnosed forms of cataract in Havanese are...
