Caudal duplication (dipygus) is an uncommon pathologic of conjoined twinning. The conjoined malformation is classified according to the nature and site of the union. We report the presence of this malformation in a female crossbreed puppy. The puppy was delivered by caesarean section following a prolonged period of dystocia. External findings showed a single head (monocephalus) and a normal cra...

OBJECTIVES To objectively quantify facial movement in response to facial expression and spoken word. DESIGN Experimental study. Setting - Department of Dental Health and Biological Sciences, University Dental Hospital, Cardiff, UK. EXPERIMENTAL VARIABLE Facial movement was assessed in response to a standardized smile expression and the utterance 'puppy'. The sequences were recorded using a ...

INTRODUCTION In April and June 2012, two outbreaks of Campylobacter gastroenteritis were investigated in an Australian aged-care facility (ACF); a Campylobacter-positive puppy was identified as a potential source of infection. METHODS An expert panel was convened to assess transmission risk from the puppy to elderly residents and to guide further public health action. Criteria considered as p...

Hip dysplasia is not a congenital defect; it is not present at birth. Multiple studies have demonstrated that all normal puppies are born with "perfect" hips; that is, they are "normal" for a newborn with no signs of dysplasia. The structures of the hip joint are cartilage at birth and only become bone as the puppy grows. If a puppy is going to develop hip dysplasia, the process begins shortly ...

T HIS COMMUNICATION presents the pathologic pattern observed in a series of experiments during which the heart of a puppy was homografted into the neck of an adult dog after the method of Mann, Priestley, Markowitz and Yater.' This method of homotransplantation may be termed a "viviperfusion"; that is, vascular anastomoses are performed between the recipient neck vessels and the puppy heart ves...

Retinal vascular development during the first three postnatal weeks was studied in 63 purebred beagle puppies. Use of a positive enzyme histochemical reaction for adenosine triphosphatase in the nuclei and nucleoli of vascular cells made visualization of the retinal vasculature possible. Animals were killed by decapitation. Thus, artifacts resulting from use of anesthetics or tracer substances ...

Recently, the world's first transgenic dogs were produced by somatic cell nuclear transfer. However, cellular senescence is a major limiting factor for producing more advanced transgenic dogs. To overcome this obstacle, we rejuvenated transgenic cells using a re-cloning technique. Fibroblasts from post-mortem red fluorescent protein (RFP) dog were reconstructed with in vivo matured oocytes and ...
