Monitoring the local Middlesex County NJ real estate market and estimating the current overall status of the market has a lot to do with DOI (Days of Inventory) or Absorption Rate. Days of Inventory (DOI) in January is 244 days.
Dogs are euthanized with an overdose injection of Pentobarbital, a liquid barbiturate commonly used to induce unconsciosness during surgery. Misconceptions. Because the euthanasia solution depresses the central nervous system, the only pain the dog will most likely feel is the needle prick when the solution is injected.
I have no clue how many dogs are euthanized in the UK... but I will say that failure to spay/neuter has little to nothing to do with the plethora of dogs being euthanized in shelters. Responsible pet owners manage their dogs reproduction... and not necessarily by spaying/neutering.
