Comparison of early socialization practices used for litters of small-scale registered dog breeders and nonregistered dog breeders

OBJECTIVE-To compare early socialization practices between litters of breeders registered with the Canine Control Council (CCC) and litters of nonregistered breeders advertising puppies for sale in a local newspaper. DESIGN-Retrospective cohort study. Animals-80 litters of purebred and mixed-breed dogs from registered (n = 40) and non-registered (40) breeders. PROCEDURES-Registered breeders were randomly selected from the CCC website, and nonregistered breeders were randomly selected from a weekly advertising newspaper. The litter sold most recently by each breeder was then enrolled in the study. Information pertaining to socialization practices for each litter was obtained through a questionnaire administered over the telephone. RESULTS-Registered breeders generally had more breeding bitches and had more litters than did nonregistered breeders. Litters of registered breeders were more likely to have been socialized with adult dogs, people of different appearances, and various environmental stimuli, compared with litters of nonregistered breeders. Litters from registered breeders were also much less likely to have been the result of an unplanned pregnancy. CONCLUSIONS AND CLINICAL RELEVANCE-Among those breeders represented, litters of registered breeders received more socialization experience, compared with litters of nonregistered breeders. People purchasing puppies from nonregistered breeders should focus on socializing their puppies between the time of purchase and 14 weeks of age. Additional research is required to determine whether puppies from nonregistered breeders are at increased risk of behavioral problems and are therefore more likely to be relinquished to animal shelters or euthanized, relative to puppies from registered breeders.  相似文献

Chlamydia psittaci: a suspected cause of reproductive loss in three Victorian horses     

R Akter  AW Stent  FM Sansom  JR Gilkerson  C Burden  JM Devlin  AR Legione  CM El-Hage 《Australian veterinary journal》2020,98(11):570-573

Chlamydia psittaci was detected by PCR in the lung and equine foetal membranes of two aborted equine foetuses and one weak foal from two different studs in Victoria, Australia. The abortions occurred in September 2019 in two mares sharing a paddock northeast of Melbourne. The weak foal was born in October 2019 in a similar geographical region and died soon after birth despite receiving veterinary care. The detection of C. psittaci DNA in the lung and equine foetal membranes of the aborted or weak foals and the absence of any other factors that are commonly associated with abortion or neonatal death suggest that this pathogen may be the cause of the reproductive loss. The detection of C. psittaci in these cases is consistent with the recent detection of C. psittaci in association with equine abortion in New South Wales. These cases in Victoria show that C. psittaci, and the zoonotic risk it poses, should be considered in association with equine reproductive loss in other areas of Australia.  相似文献

The action of formamidines on octopamine receptors in the locust     

Anthony P. Davenport  David B. Morton  Peter D. Evans 《Pesticide biochemistry and physiology》1985,24(1):45-52

The actions of a range of formamidines have been investigated biochemically and physiologically on octopamine receptors in the locust Schistocerca gregaria. All the formamidines tested [chlordimeform (CDM), demethylchlordimeform (DCDM), amitraz, and UK 16353] mimicked the action of octopamine by (1) increasing the amplitude and relaxation rate of slow motorneurone tension in the extensor-tibiae muscle of the hind leg and (2) changing the levels of cyclic AMP in this muscle. UK 16353 was most effective in changing these parameters, followed by DCDM then amitraz and CDM. The formamidine-induced increase in cyclic AMP levels was reduced or completely blocked by phentolamine, an antagonist of insect octopamine receptors. The time course for the increase in cyclic AMP was followed for 30 min by incubating muscles in 10^?5M DCDM. The increase was potentiated by the phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine. In the presence of this compound, the response peaked within 5 min, before declining to a lower plateau after 12 min. The response to 10^?5M CDM was lower and the maximum increase occurred after 7 min, then rapidly declined. Both formamidines increased cyclic AMP in a dose-dependent way with a threshold of between 5 × 10^?7 and 10^?8M. The results are discused in terms of the relationship between the biochemical and physiological actions of the formamidines in this preparation.  相似文献   

Malignant histiocytosis in four dogs   总被引：1，自引：0，他引：1  

M L Wellman  D J Davenport  D Morton  R M Jacobs 《Journal of the American Veterinary Medical Association》1985,187(9):919-921

The clinical and pathologic features of 4 dogs with malignant histiocytosis were evaluated. The most common clinical signs were weight loss, lethargy, lymphadenopathy, hepatosplenomegaly, and anemia. Neoplastic histiocytic infiltrates most commonly were found in the spleen, bone marrow, liver, or lymph nodes. Malignant histiocytosis was considered as a differential diagnosis for anemic dogs with lymphadenopathy and/or hepatosplenomegaly.  相似文献   

Susceptibility of male white-tailed deer (Odocoileus virginianus) to Brucella ovis infection     

S J Barron  A A Kocan  R J Morton  T R Thedford  C S McCain 《American journal of veterinary research》1985,46(8):1762-1764

Infection with Brucella ovis was established by conjunctival instillation in 8 male white-tailed deer (Odocoileus virginianus). Infection was transient in young bucks, but persisted in bucks that were mature when inoculated. The deer were euthanatized and necropsied at various intervals after inoculation. Brucella ovis was recovered from a mature buck at necropsy on postinoculation day 429. Four deer had gross lesions and histopathologic changes of the epididymides. A mature noninfected buck confined for 7 months with an infected buck acquired infection and developed epididymal lesions.  相似文献
