Relationship between the serum concentrations of serotonin and lipids and aggression in dogs

Vet Rec. 2007 Jul 14;161(2):59-61. doi: 10.1136/vr.161.2.59.

Abstract

The serum concentrations of serotonin and lipids--triglycerides, total cholesterol, low density lipoprotein, high density lipoprotein and very low density lipoprotein--were determined in 18 normal dogs and 23 dogs diagnosed as aggressive on the basis of interviews with their owners and an assessment of their behaviour with reference to a canine overt aggression chart. The serum serotonin levels in the aggressive dogs were significantly lower than in the normal dogs (P<0.01), but the differences in serum lipids between the two groups were not statistically significant.
