Study dayĪnalysis of baseline thunder test and group assignment However, have a look at their experimental schedule. They found that a DAP collar reduced global measures of anxiety and active signs of anxiety and increased the use of a den. One better study uses normal dogs and exposed them to thunder sounds at 83.9 dB (thunder itself can be up to 130dB). Two very problematic studies (discarded 5,8) are often quoted but neither are placebo-controlled, and both use other treatments simultaneously. There is only minimal evidence that Adaptil helps dogs with sound‐induced fear and anxiety. Just a warning though: barking is a complex problem, and Adaptil would probably only help in those dogs where it is caused by anxiety. My view: although the study has some statistical problems 2, it seems likely that the effect is real. Dogs exposed to a person walking by or a friendly person barked less often and the average loudness was reduced compared with placebo. One study 11 on dogs in a shelter provides indirect evidence that Adaptil can reduce the intensity of barking. Of course, it is harmless to try as long as it’s not used instead of a more effective remedy. However, separation anxiety is usually severe by the time a vet is consulted, so I am not surprised that a mild treatment like DAP had no measurable effect. My view: the results could have been different if dogs who suffer from separation anxiety were used instead. Normal dogs were separated from their owners in a laboratory setting and observed for signs of anxiety. The one good study 13 found that a DAP diffuser did not improve behaviours such as barking, scratching, whining, howling, trembling, nor heart rate, eye or ear temperature of dogs. There is no high quality evidence that Adaptil works for separation anxiety in dogs. These are often the same studies being quoted at you to say Adaptil works. You can read why here.įor this reason, I have discarded 8 studies ( listed below) that all found benefit without comparison to placebo. ![]() I will just say that any behavioural study without a placebo group is very likely to find that the drug works, whether it does or not. The lack of placebo control is a bigger problem. This is a subtle form of bias because if we remove studies that say something doesn’t work, it can make uncertain efficacy seem certain. One thing companies definitely do not do often is publish studies that don’t give the desired outcome. This will come up especially when I talk about puppies later. Of course, just because a career or a study depends on the whims of a pharmaceutical company doesn’t mean the science will be bad. Many studies are not placebo-controlled.Many studies or researchers are directly funded by the company that owns the molecule.While there are some excellent studies among the 20 available, there are also two large problems: I’ll present the evidence under headings for each condition or problem. You’ll see that different studies used different products. a spray bottle for daily use around the house or on wearable items.a treated collar, which also lasts 1 month. ![]()
