17 We must painfully acknowledge that, precisely because of its great intellectual development, the best of man’s domesticated animals - the dog - most often becomes the victim of physiological experiments. It is extremely touching. The dog is almost a participant in the experiments conducted upon it, greatly facilitating the success of the research by its understanding and compliance (Pavlov 1893) "When I dissect and destroy a living animal, I hear within myself a bitter reproach that with rough and blundering hand I am crushing an incomparable artistic mechanism. But I endure this in the interest of truth, for the benefit of humanity"

18 "this method was adopted as a result of a hint given by one of the dogs subjected to the operation. We (dr. Kuvshinski and I) gratefully acknowledge that by its manifestation of common sense the dog has helped us as well as itself” “I regard the promotion of our surgical technique to be a matter of greatest importance, because the usual method of simply vivisecting the animal in an acute experiment is, as is now becoming clearer day by day, a major source of error, since the act of crude violation of the organism is accompanied by a mass of inhibitory influences on the functions of the different organs. The organism as a whole, the realization of the most delicate and most expedient linking of an enormous number of separate parts, cannot, in the nature of things, remain passive to destructive agents”

19 “The desire... to spare our experimental animals as much as possible made us stricktly observe all the precautions taken by surgeons in respect to their patients” "Our healthy and happy animals did their laboratory work with real gusto; they always rushed from their cages to the laboratory and readily jumped on the tables where our experiments and observations were conducted. Believe me I am not exaggerating a iota. Thanks to our surgical method in physiology we can demonstrate [phenomena of digestion] without a single scream from the animal undergoing the experiment”

20 “In almost all biological experiment, particularly in hormone research, the rat has made a place of honour for itself. Because of its cooperation, though involuntary, he has contributed to countless and important successes. I feel that I am not only fulfilling a debt of gratitude towards the rat but contributing something towards its rehabilitation and recognition by taking this opportunity to protest against the prejudice of the public towards these, my favourite test animals, and I would like to convert my readers from the abhorrence in which these really inoffensive little animals and their habits are so often held” (Eugene Steinach)

21 “Pavlov cultivated the image of laboratory dogs that, after recovering from the surgical operations, led normal, ‘happy’ lives. The reality was somewhat different. Many dogs died and survivors usually developed fatal conditions... Whether or not they were happy and normal, they lived much longer than those consumed in acute experiments and this facilitated a relationship with experimental dogs that sometimes resembled that between pet and master” (Daniel Todes, 2002, p. 98).

34 Verslaving Een onderzoeksgroep wil het verband onderzoeken tussen traumatische jeugdervaringen (zoals emotionele verwaarlozing op jonge leeftijd) en de incidentie van verslaving aan alcohol of drugs. Daartoe willen ze gebruik maken van proefdieren. Het gaat om 40 ratten (20 ratten in de controle-conditie, 20 ratten in de experimentele conditie). De ratten in de controle-conditie groeien op bij hun moeder. Hun soortgenoten in de experimentele conditie worden op jonge leeftijd van hun moeder gescheiden. Wanneer de dieren volwassen zijn, worden ze in een speciale kooi geplaatst waar ze zich zelf met behulp van een pedaaltje alcohol of cocaïne kunnen toedienen. De hypothese is dat ratten in de experimentele conditie sneller verslaafd zullen raken dan ratten in de experimentele conditie. Na 3 weken worden de dieren gedood met het oog op anatomisch onderzoek van relevante hersengebieden. Ze leggen hun protocol voor aan de DEC en benadrukken het maatschappelijke belang van hun project. Verslaving is immers een ernstig (en kostbaar) maatschappelijk probleem. Ze vewachten dat hun onderzoek de mogelijkheden voor preventie zullen bevorderen.
