A four-month-old, female boxer developed severe inspiratory dyspnea three days after elective ear crop surgery. Radiographs confirmed the diagnosis of collapse of the distal cervical trachea. The puppy was treated with oxygen, aminophylline, and ampicillin, but required emergency tracheostomy to stent the collapsed region. Clinical signs resolved following application of five polypropylene total-ring prostheses, and the puppy continued to do well despite significant growth to maturity.  相似文献

A nine-month-old puppy was presented for investigation of seizures. Neurological deficits were found localising to the prosencephalon, mesencephalon and myelencephalon. Magnetic resonance imaging identified multiple, large lesions involving both cerebral hemispheres. Management with antiepileptic and immunomodulatory drugs was instituted; however, the seizures became progressively refractory and the puppy was euthanased. Histopathology following post-mortem examination found a mixed glial cell tumour with discrete areas where neoplastic cells appeared oligodendroglial or astrocytic. Primary intracranial neoplasia is a rare cause of neurological disease in young dogs. Moreover, this case is unusual in terms of both the mixed glial nature of the neoplasm and also its multi-focal distribution.  相似文献

Eleven German Shepherd dogs with pituitary dwarfism were examined. They were severely stunted in growth and possessed abnormal hair coats with persistence of the soft puppy (lanugo) coat and symmetrical areas of alopecia. Various other physical defects were often present in affected dogs. Detailed hormonal studies demonstrated a severe deficiency in growth hormone in all five cases so evaluated. A decrease in somatomedin activity was present in three of these cases. Changes in growth plates epiphyses and ossification centres were apparent on radiographic examination of four of the eleven dogs. Epiphyseal dysgenesis was confirmed histologically in two of these cases. Of the six brains which were examined post mortem, four showed large cystic lesions involving the adenohypo–physis and two had pituitary hypoplasia with virtual absence of adenohy–pophyseal tissue.  相似文献

Objective: To describe the case management for a dog diagnosed with a nasopharyngeal polyp.
Case summary: A 9-week-old Shar-Pei puppy presented for progressive dyspnea and collapse. Clinical signs were consistent with an upper airway obstruction (UAO) and a temporary tracheostomy was performed. The puppy was at first diagnosed with and treated for brachycephalic airway syndrome but continued to exhibit signs of an UAO after soft palate resection. Nasopharyngoscopy revealed a nasopharyngeal polyp causing the UAO, which was surgically removed. The puppy has been free of clinical signs for 1 year after removal of the polyp.
New or unique information provided: This is the first report of a nasopharyngeal polyp causing a life-threatening UAO in a puppy. It emphasizes the importance of examining the nasopharyngeal space in neonates presenting with UAO.  相似文献

The Internet is an increasingly common way for consumers to purchase puppies. Yet very little information is available about the types of puppies sold via the Internet. In addition these sales are not subject to United States Depart of Agriculture (USDA) regulation. The objectives of the study were to describe puppies sold via the Internet, to assess the characteristics that contribute to the cost of a puppy, and to compare puppies sold via the Internet with puppies sold by American Kennel Club (AKC) Parent Club breeders. Over 14 weeks in 2008, Yorkshire Terrier, Shih Tzu, English Bulldog, Boxer, and Labrador Retriever puppies for sale on two large-scale online puppy sales sites were categorized based on their Internet advertisements. Data were collected in three categories: puppy characteristics, health characteristics, and policies (such as spay/neuter requirement, health guarantee, and return policy). After the survey was completed, 25 AKC Parent Club breeders and 25 other breeders who advertised via one of the puppy sales websites were randomly selected and interviewed over the phone. Small breed puppies were most frequently advertised with 35.2% (1228/3485) of advertisements for Yorkshire Terriers and 23.0% (802/3485) for Shih Tzus. Almost one quarter of Internet breeders 768/3474 (22.2%) advertised four or more different dog breeds. Champion bloodlines increased the cost of a puppy of all breeds. AKC Parent Club breeders 21/25 (84%) were more likely to mention breed-specific health screening tests when compared to Internet breeders 7/25 (28%). Consumers should apply the same standards for purchasing from a breeder found through a puppy sales site as they would for purchasing from a local breeder. Breeders who advertise at one of the large-scale puppy sales websites are less knowledgeable about breed-specific health issues compared to an AKC Parent Club breeder. Internet breeders are less likely to perform these screening tests on their breeding dogs and may breed dogs with undesirable heritable health risks.  相似文献

A 3‐month‐old female Basset Hound‐Shar Pei mix puppy (Ba‐Shar or Sharp Asset) presented with oral bleeding due to a cracked molar. On physical exam, an aural hematoma was also noted that the owner indicated was chronic. The puppy was hospitalized for over 24 h until the bleeding was brought under control. At 4 months of age, the puppy again presented with oral bleeding due to loss of deciduous teeth and was hospitalized until bleeding was controlled. Coagulation screening tests, platelet numbers, and von Willebrand Factor antigen levels were within reference limits. Based on the presence of platelet‐type bleeding in the face of normal screening test results, samples were submitted for DNA testing for Basset Hound thrombopathia. The puppy tested as affected for the calcium and diacylglycerol regulated guanine nucleotide exchange factor I (CalDAG‐GEFI) mutation causing this disorder. This is the first time thrombopathia has been diagnosed in a “designer” breed.  相似文献

A 6-month-old, intact male Great Dane dog fed a veterinary therapeutic liver diet was evaluated after diagnosis of an intrahepatic portosystemic shunt and hind limb angular limb deformity to determine appropriateness of diet. Evaluation of the current diet revealed it to be inadequate to meet the nutrient requirements of a large breed puppy. The dog clinically improved following a change in diet. There was no longer any angular limb deformity and no reported neurological signs. This report highlights the importance of appropriate feeding management during growth and demonstrates that although veterinary therapeutic diets may appear to be an appropriate choice initially, they may not be ideal for growing puppies as a long-term feeding option.Key clinical message:An individual approach is key for nutritional management of complicated canine veterinary medical cases and includes consideration of the patient’s life stage requirements when modifying nutrient intake to manage clinical disease.  相似文献

A 4-month-old Maltese puppy and a 7.5-year-old Collie were diagnosed with septicemia associated with Citrobacter freundii. The puppy died soon, after developing weakness and mucohemorragic diarrhea. The Collie had immune-mediated hemolytic anemia and thrombocytopenia and was treated with immunosuppressive drugs before being euthanized. Gross examination of the puppy revealed mucohemorrhagic intestinal contents. Focal necrotic hepatitis, fibrinous peritonitis, interstitial pneumonia, and hemorrhagic gastrointestinal contents were observed in the older dog. Histologically, there was a diffuse, moderate, histiocytic meningitis in the puppy and a focal fibrinonecrotic hepatitis in the adult dog. Lesions in both dogs contained numerous gram-negative rods. Citrobacter freudii is a potential cause of monomicrobic bacteraemia-septicemia in puppies or immunocompromized adult dogs.The gastrointestinal tract is probably the main site of entry.  相似文献

Neonatal mortality rate (NMR) may be affected by maternal physical condition, anesthesia, and uterine incision or en-bloc neonate removal. The association of selected factors with number of dogs with dead puppies at hospital discharge was evaluated using 78 records. Data obtained at admittance for emergency cesarean section included: age, small or large body size, rectal temperature, packed cell volume, serum total protein, blood urea nitrogen, glucose, puppy in pelvic canal, and heart rate. Administration of opioids, propofol, alfaxalone, isoflurane, and sevoflurane, and anesthesia/surgical times and surgical technique were evaluated using Fisher’s exact tests. There were 238 live puppies and 38 dogs had 58 dead puppies; the NMR was 19.6%. Mortality was associated with puppy in the pelvic canal (P = 0.003) and duration of anesthesia > 80 minutes (P = 0.029). Age > 8 years (P = 0.054) and induction time to start of surgery > 30 minutes (P = 0.17) may be associated with mortality. Expedient cesarean section with obstructive dystocia and an induction time to start of surgery < 30 minutes are important for puppy survival.  相似文献

A review of coccidiosis in dogs is given on the basis of an autopsy of a puppy from a kennel in which other puppies had diarrhoea and stunted growth. Coccidiosis especially affects puppies from kennels and leads to poor growth, diarrhoea, and even death. Its occurrence is probably underestimated.  相似文献

Here we report a case of canine babesiosis with unusual morphology of the causative agent. A male, seven-week-old Labrador retriever puppy, exhibiting severe anaemia and haemoglobinuria, was presented at the Clinic of Internal Medicine in February 2011. The puppy was euthanised. The most relevant pathological changes were icterus, severe splenomegaly, generalised lymphadenopathy and haemoglobin nephrosis. Samples were collected from various organs for histology within one hour post mortem. Impression smears were also prepared from the spleen after overnight storage at 4 °C. Tissue sections and smears showed the presence of multiple, coccoid intraerythrocytic bodies that measured 1-2 μm and resembled small babesiae. No large piroplasms were seen. DNA was extracted from the spleen, and a conventional PCR was performed for the amplification of a 450-bp region of the 18S rRNA gene of piroplasms. The causative agent was identified as Babesia canis canis, with 99% sequence identity to other European isolates. Sequence identity to B. gibsoni was only 91%. This is the first account to verify that the morphology of the large canine piroplasm, B. canis, can be uniformly small babesia-like post mortem or following the storage of tissue samples.  相似文献

Multisystemic chromatolytic neuronal degeneration, a newly recognized disease of Cairn Terriers, is described in a second affected North American puppy. In this puppy, the early onset of hind limb weakness at 11 weeks and rapid development of signs of diffuse CNS involvement were distinctive. Signs of cerebellar dysfunction were prominent, but bouts of cataplectic collapse in this puppy constituted the most distinguishing clinical feature. Although electroencephalograph (EEG) recordings lacked a true rapid eye movement (REM) pattern during cataplectic episodes, cervical electromyograph (EMG) potentials ceased or diminished, and imipramine injection was associated with arousal. Postmortem studies revealed that chromatolytic degeneration was very widespread, affecting many neuronal populations in the brain and spinal cord as well as neurons in sensory ganglia. Although the pattern of chromatolysis varied among affected perikarya, chromatolysis was consistently related to dispersion and loss of ribosomes. In this puppy, as opposed to six studied previously, thoracolumbar myelomalacia also occurred symmetrically in the dorsal horns and adjoining funicular white matter. The metabolic derangement underlying this chromatolytic neuronal degeneration and myelomalacia remains unknown.  相似文献

To ensure an optimal growth is crucial in raising healthy dogs, especially in large and giant breeds. Dogs with a moderate growth velocity tend to have lesser problems with developmental orthopaedic diseases than those with forced or maximum weight gain. In this study, the energy needs of growing dogs from two different breeds (Beagles as a medium‐size breed and Foxhound crossbreds as a large‐size breed) to ensure a growth development as recommended by the National Research Council (NRC) were determined at the age of 6–28 weeks. After weaning at the age of 6 weeks, the food rations sufficient to meet the energy requirements of each individual puppy were adjusted every other day according to growth level, guaranteeing a development consistent with the recommended weight curve for the respective breed size. The food and therefore energy intake of the puppies was registered daily; it ranged from 0.72 to 2.34 times the maintenance requirements with little effect of age. During the whole period, however, there was a consistent breed difference: Foxhound‐Boxer‐Ingelheim Labrador crossbreds (FBIs) had higher energy intakes expressed as multiples of maintenance than Beagles, suggesting that during the major period of growth, the energy requirement is not a function of age. Adult Beagles and FBIs showed similar differences in energy requirements as already during growth as shown in this study. This indicates that breed differences in energy requirements have already to be taken into account during growth. On the other hand, the results showed clearly lower energy needs for growth in these two different breeds than recommended in the NRC.  相似文献

After showing clinical and radiographic signs of a gastrointestinal foreign body, a 5-month-old puppy began head pressing, which progressed to convulsions. Hematological abnormalities suggested lead poisoning; serum lead was 2.61 mumol/L. The puppy made a complete recovery after intensive treatment for lead toxicosis.  相似文献

Concurrent Cryptosporidium and parvovirus infections in a puppy   总被引：2，自引：0，他引：2  
Cryptosporidium parvum, an intestinal coccidian parasite, was isolated from faeces and intestinal biopsies of a 9-week-old puppy with acute parvoviral gastroenteritis. Gene sequence analysis identified a Cryptosporidium genotype not previously recorded in Australia. The puppy recovered after treatment with crystalloid fluids, synthetic and natural colloids and jejunostomy tube feeding.  相似文献
