In the US, about 6.3 million companion animals enter shelters every year, and roughly 390,000 are identified as abandoned by their own caregivers. Across the UK and Australia, the reasons and risks shift sharply, from housing constraints and moving stress to post adoption behavior issues and cost barriers. This post pulls together recent, location specific statistics so you can see what is driving surrender most often and where change is starting to work.
