It seems that the dog overpopulation in Belgrade is similar to that of many other cities in the world. However, Belgrade does not have problems with inhumane stray dogs' population control methods, nor with their malnutrition, nor with inadequate veterinary care. Moreover, Belgrade has a problem with irresponsible and uneducated dog owners, stray and abandoned dogs on the streets and many unlicensed private animal shelters. The next problem is the existence of only one municipal shelter for abandoned, relinquished pets and stray dogs and cats in Belgrade. The first aim of the study was to estimate the total number and the ratio of dogs that were relinquished to the municipal shelter for adoption and for euthanasia in the period from 1st January 2004 to 31st December 2007. The second aim of the study was to estimate the main reasons for relinquishment of owned dogs for adoption and reasons for euthanasia in the municipal shelter in Belgrade. The most owned dogs were relinquished for euthanasia (N=1005; 86.563%). Only 156 dogs (13.437%) were relinquished for adoption. Therefore, the number of relinquished dogs for euthanasia was significantly higher than the number of relinquished dogs for adoption (P<0.001). Financial problems were the most frequently given reasons for relinquishment of dogs to the municipal shelter for adoption (26.92%). The leading cause of relinquishment of dogs to the municipal shelter for euthanasia was incurable illness of aged dogs (25.77%)

The aim of the study was to analyse the demographic characteristics of lost and found dogs in Belgrade, Serbia. The demographic data concerning the 246 lost and 81 found dogs in the period of 5 consecutive years (January, 2009 to January 2014) was sampled and analysed from the data bases of four organizations for animal protection in Belgrade. The recovery rate of lost dogs and the chance to be reunited again with their owners was 33%. The highest recovery rate was estimated in the category of lost dogs with visible marks such as tags or collars (30%).The chi-square test disclosed that besides dogs with special visible marks, significantly more females, light colour coated, friendly/sociable and neutered dogs were reunited with their owners (P<0.0001).

The prevalence of canine noise-related fears was studied by the questionnaire method of dogs’ owners from different part of Belgrade. Dog-owners (N=147) were chosen from a variety of sources (permissive municipal areas and parks for walking of dogs, dog shows and exhibitions and veterinary surgeries for small animal practice). Owners indicated noise-related fears in 59 dogs (40.14%). Twenty-six (17.69%) of them were mixed breed dogs and 33 (22.45%) were pure breed dogs. Noise-related fears were indicated in 25 females (17.01%) and in 34 (23.13%) males and, in 27 (18.37%) intact and 32 (21.77%) neutered dogs. From 59 dogs with noise-related fears 13 of them (8.84%) were directly purchased from breeders and 46 (31.30%) were obtained from other sources. There was a statistically significant difference (p<0.001) in the rate of noise-related fears between the dogs directly purchased from breeders and dogs obtained from other sources
