Hopefully this recession will have a positive side when people decide that they would rather feed themselves than a dog, so that dog ownership goes down.
Vets are reporting a reduction in the number of dogs being immunised against canine parvovirus

and blame the recession for the reduction.
The virus is extremely hardy and has been found to survive in feces and other organic material such as soil for over a year. It survives extremely cold and hot temperatures
So those irresponsible dog owners who dont pick up the poop may well cause an epidemic which will result in a 'natural cull' of the dog population
