Indirekt blodtrycksmätning hos hund och katt :
The objective of this study was to study the agreement between two methods of indirect bloodpressure measurement in dogs and cats and to establish the within-method variation for the methods. The utility and practicality in the clinical setting were also evaluated for the both methods. The techniques evaluated were the oscillometric method and the Doppler ultrasonographic method. Thirtytwo dogs and 26 cats were used in the study and seven dogs and five cats out of these animals had diseases that may effect the bloodpressure. Bloodpressure was measured in both anesthetized and in conscious animals.
Skiljer sig hundvalpars lekbeteende åt mellan raser och kön? :
There are many theories why animals play but none have jet been proven. During observation on Canids, play seems to be important when they learn to control the intensity of the bite and to facilitate the social structure within a group. When dogs play they perform behaviours that otherwise are used during hunting, reproduction and aggression that in another context would be for example hostile. The dog is one of the species that we humans have domesticated and they have been exposed to an intense and concentrated breeding so they can function in different areas, for example herding and hunting. This breeding has resulted in that the pure bred dogs can be very different between the breeds.
Immunohistochemical detection of thymidine kinase 1 in canine mammary tumors and lymphomas
The dog has often served as a model animal for humans in scientific studies. This is due to the fact that dogs are susceptible to a wide range of diseases which also affect humans. One example is cancer, a condition that affects dogs as well as owners. Neoplastic diseases account for 18-23 % of all deaths in dogs (Bonnet et al., 2005 and Jagielski et al., 2002).
Mammary tumor, or tumor of the breast, is the most common tumor form in intact dogs and women (Im et al., 2013). Mammary tumors originate in the udder, and are classified according to their histological characteristics.
Castration coverage and attitudes towards a castration program in Lilongwe, Malawi
The aim of this study was to measure the castration coverage and the attitudes among people towards castration in an area in Lilongwe, the capital of Malawi, where a castration program has been running for a few years. Another aim was to review the literature to examine the link between castration coverage and rabies prevalence. Two areas (Area 25 and Area 23) in Lilongwe were studied through standardized household interviews. In Area 25, a non-governmental organization had been castrating dogs weekly to twice weekly for free for 3 years. In Area 23, no official organization had done castrations, and this area therefore acted as a control in the study.
Use of dogs as odour detectors : a review of the scientific literture
A lot of various substances can be detected by dogs, as oestrous in cows, endangered species or non-biological substances like accelerants, narcotics, explosives, mines and pollutions and biological substances like identity (suspects), cancer (breast, lung, colorectal and bladder cancer), human remains (cadaver), bacteria and mould in buildings. The dogs are trained using non-scientific methods and not much research in detection training exists. This is a review of different types of dog detection, with focus on new research..
Höftledsdysplasi och armbågsledsartros hos labrador retriever med känt radiologiskt status av höftleder och armbågar : en tredje uppföljande studie
Joint-related diseases including hip dysplasia (HD) and elbow arthritis (ED) can in advance cases lead to that the dog has to be put down, and these diseases are also the cause to expensive veterinary treatments of many large breeds, including Labrador Retrievers. The aim of this study was to make a follow-up study on the 271 Labradors, who previously participated in a study on the effect of nutrition and exercise on hip and elbow status in a birth cohort born year 2000. That study investigated the relationship between nutrition, exercise, and HD and ED. A follow up study on the same dogs at 5-6 years of age investigated the clinical effects of the radiological hip and elbow status at 1 years of age and if was effected by body condition score. This study took place in 2011-2012 and 187 Labrador retrievers participated.
Påvisande av Helicobacter spp hos hund : en metodologisk studie
The purpose of this study was to develop a reliable molecular-genetic method to determine the different species of helicobacter in dogs. The study is part of a larger project to map the prevalence of Helicobacter spp in healthy and sick dogs in Sweden, and to determine the possible connection of Helicobacter spp infection with gastrointestinal diseases in dogs.
Several published studies have reported on the prevalence of Helicobacter spp in dogs. The problem is that three of the most common species are so alike that a 16SrRNA-PCR with sequencing is not able to differentiate between them. In this study, DNA has been purified from samples and then a Multiplex PCR has been performed. Multiplex PCRs use multiple primers in one single PCR.
Orsaker till trombocytopeni hos hund : en retrospektiv studie av 123 fall
Causes of thrombocytopenia in dogs ? a retrospective study of 123 cases
The purpose of this retrospective case study was to determine which diseases are associated with thrombocytopenia in Swedish dogs. Records of 123 dogs with thrombocytopenia were evaluated. The most common cause was neoplasia-associated thrombocytopenia (32%). The largest proportion within this group was unspecified neoplasia.
Svensk tjänstehundsavel : en återblick och nutidsbeskrivning samt förslag inför framtiden
In 1936 a governmental breeding project was started with aim on military use. The police later came to use dogs from this project as well. In order to utilize dogs that could fit for other purposes training and education of dogs for search of different substances and of guide dogs for blind persons was performed. A political decision to privatize the whole dog programme was taken in 1992.
During most part of the time one had serious economical issues since too few of the dogs that were bred could be considered to fulfil the basic demands for service. To satisfy the need of service dogs private bred dogs were bought as well.
Förekomst av Giardia i symtomfria valpkullar :
The flagellate Giardia intestinalis has been known to cause diarrhea in both man and
dog. Results from epidemiological studies have indicated that transmission of the
parasite from dog to man is plausible even though that route of infection has yet to be
shown. Several international studies have shown that the parasite frequently occurs in
asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not
known though. In this study, faecal samples were collected at two separate occasions
from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract.
The samples from each litter were pooled but the samples from the bitches were
analyzed individually.
Människovana grävlingar som testdjur för grythundar. En studie om hur grävlingars beteende och fysiologi påverkas av hundars aggressivitet
In Sweden live badgers are used in tests in order to train and prepare earth dogs for hunting underneath ground. This has for several years causeddebate concerning the welfare of the badgers. It is questioned whether the purpose of the dog training, i.e. to reduce injuries in both dogs and prey, is worth the suffering that is reflected on the badgers. The aim of this investigation was to study 1) stress levels in badgers when used in earth dog training, 2) if the stress load differs when the badgers are exposed to dogs with varying aggression levels (low, moderate, high).
Perception of human acoustic communication in the domestic dog (Canis familiaris)
For most dog owners today it is natural to use acoustic stimuli such as talking to communicate with their pets. Words are used both to ask the dogs to perform tricks, as well as to hold ?conversations? with the dog. This literature review looks at how dogs perceive human acoustical communication and how this can influence the behaviour of the dog. This information could be used e.g.
Social struktur och dominans hos hund
The dog (Canis lupus familiaris) is the first species ever domesticated. They can develop a close bond towards other dogs, almost like a relationship among siblings, which can be a high valuable resource for good relations and cooperation?s.
Dominance in dogs is sometimes used to explain undesired behaviors and explained as a personality trait. Dominance though, is not a trait in a dog or a source for undesired behaviors, but can rather be explained as a relationship between individuals, were one of them receives more submissive signals from the other.
Sederingsrutinens påverkan på resultatet av höftledsröntgen : en pilotstudie
Hip dysplasia is a common, inherited malformation of the coxofemoral joint that
eventually leads to osteoarthrosis. Several breeds of dogs are affected and the
prevalence varies between different breeds. As part of the effort to reduce the
prevalence of hip dysplasia and select dogs suitable for breeding, radiological
screening is performed by at least 12 months of age. Before the radiological
examination the dog has to be chemically restrained, sedated or anesthetized. The
sedation protocol used differs between veterinary clinics.
The impact of sedation method of the screening result for hip dysplasia has been
studied.
Injektion till katt ? injektionsassocierad smärta samt injektioner i praktiken
Intramuscular injections to cats can generate strong reactions in some individuals while reactions of the same extent, according to the author, not always are recognized when using the subcutaneous route. The reactions are probably caused by fear, stress and/or pain.
When the injection can generate pain one has to take that into account, which can be a limitation in treatment. It is well known that injections generate pain, but knowledge about the cause and processes of the injection-associated pain is limited. This is mainly due to the difficulty in finding objects to study pain on, high cost of use of laboratory animals and difficulty to obtain objective measurements. Although there is evidence that there may be a local muscle injury by intramuscular injection, it is not always that the extent of damage is related to the pain experienced.
Facts about the causes of injection-associated pain have been studied in a literature review.
