Studies About Dogs

Recommended Posts

Hi DOLers,

Troy has given me permission to start a thread to gather information about research and studies about dogs. He will pin this one.

If you've located or read a study about some aspect of our canine friends could you please place the following information here.

* Research/study title

* Brief summary of research topic/findings

* Link to research or institution that holds it

* Brief comment on the study

If people want to discuss a particular study, can they please start another thread? That way this one can simply be a source for those looking for particular research. ;)

Sorry your pup died.   However many many pups are killed by parvo, and without vaccination the numbers would be staggering.  A lot of testing has been done on vaccines, and the preponderance of eviden

This is a study on Mandatory Desexing in ACT

written by the AVA's Centre for Companion Animals in the Community.

and how/why it did not work.


the report also offers insight into the notion of 'overpopulation' wrt the numbers of cats/dogs euthanased in Australia each year.

The issue of unwanted animals: Adopting a strategic and practical approach


This is a study on the number of cats/dogs being euthanased in Australian pounds written by the AVA's Centre for Companion Animals in the Community.

It exposes the myth of 'pet overpopulation' and rather calls for the need for a holistic approach that address the complexity of the issues at hand.

Comments: Discusses the term 'pet overpopulation' and looks at Australian facts and data.

National study of the gastrointestinal parasites of dogs and cats in Australia


The prevalence of gastrointestinal parasites in Australian pet dogs and cats was largely unknown prior to this study. Current recommendations for the prophylactic treatment of parasites in Australia are based on studies conducted 20–30 years ago. A total of 1400 canine and 1063 feline faecal samples were collected from veterinary clinics and refuges from across Australia. The overall prevalence of gastrointestinal parasites in dogs and cats was 23.9% (CI 21.7–26.1) and 18.4% (CI 16.1–20.7), respectively. Overall Giardia was the most prevalent parasite in dogs (9.3% CI 7.8–10.8) followed by hookworm (6.7% CI 5.4–8.0). Isospora felis was the most prevalent parasite in cats (5.6% CI 4.2–7.0), followed by Toxocara cati (3.2% CI 2.1–4.3). In conclusion the prevalence of intestinal helminths in Australian pet dogs and cats is low. Consequently, consideration should be given to the future use of anthelmintics and continued emphasis on pet owner education as means of preventing infection.

A number of species are considered to use functionally referential signals such as alarm calls or food-related vocalizations. However, this particular function of communicative interaction has not previously been found in canids. We provide the first experimental indication that domestic dogs, Canis familiaris, rely on context-dependent signals during interspecific agonistic encounters. We recorded several sequences of growls from dogs in three different contexts: during play, guarding a bone from another dog, and reacting to a threatening stranger. We analysed the acoustic structure of the growls and additionally performed playback tests in a seminatural food-guarding situation. We found that play growls differed acoustically from the other two (agonistic) types of growls, mainly in their fundamental frequencies and formant dispersions. Results of the playback experiment showed that food-guarding growls deterred other dogs from taking away a seemingly unattended bone more effectively than growls recorded in the threatening stranger situation. We ruled out an effect of the signaller's body weight on the subjects' responses. These results provide the first evidence of context specificity of agonistic vocalizations in the dog. We discuss the possible aspects of honesty and deception through acoustic modulation of growls.

An article from the USA giving useful links re vaccinosis


This is a very good article. Have you read the book "The Nature of Animal Healing"? by Dr Martin Goldstein,D.V.M. He has had much the same experience, seeing many animals having bad reactions to vaccines, long and short term. There seems to be a plethora of information on Vaccinosis becoming available. :hug:

A Comparison of Tethering and Pen

Confinement of Dogs

There was no indication that tethering

was more detrimental to the dogs’ welfare than housing in a pen.

Although tethering is intuitively less acceptable, the fact that the dogs rarely

pulled at their chains and the lack of major differences in behavior indicate that

tethering may be an acceptable alternative housing method, but this may depend

on the breed and experience of the dog.

It concerns me greatly that dog registration bodies require that all pups should be vaccinated when there is so much evidence that vaccines are making our animals sick. :thumbsup:

Well, the "evidence" is anecdotal. That's why it's not being taken seriously. Because there is no scientific evidence to support it yet. Scientists did loads of research into it for humans years ago and concluded that the benefits far outweighed the risks.

Here's a link to a recent paper on the inheritance of the colour pattern known as domino in Afghans and as grizzle in Salukis. The inheritance of this pattern has not been well studied previously. In my lay person's summary, the study finds that domino and grizzle are a variation of black and tan, at/at, with the expression of the black and tan affected by a newly identified allele in the E series they suggest calling EG. The authors think that EG is dominant to E and e, but recessive to Em. Kb and ay seem to suppress the expression of EG, and therefore of the domino and grizzle patterns.

Title: Impact of nutrition on canine behaviour: current status and possible mechanisms

Nutrition Research Reviews (2007), 20, 180–194

Authors: G. Bosch, B. Beerda, W. H. Hendriks, A. F. B. van der Poel and M. W. A. Verstegen

A paper I stumbled across about how nutrition may improve dog behaviour and therefore welfare. It's a bit heavy, but might be interesting for some folks.
