Statistics on pet abandonment are very hard to come by so like for like comparisons (within or between countries) are almost impossible. However, some organisations do compile certain data and we have captured a few pieces below. We will continue to add to this as we come by relevant statistics.
Australia
The RSPCA (Royal Society for the Prevention of Cruelty to Animals) receives thousands of animals every year. Statistics on the numbers of animals received, reclaimed or rehomed are compiled on a national basis by RSPCA Australia and published annually on their website. During 2015-2016 they received about 45,000 dogs and 55,500 cats. Of these, 13% of dogs and 30% of cats were euthanised.
It is a criminal offence in all Australian States and Territories to abandon an animal of a species usually kept in a state of confinement or for a domestic purpose.

UAE
It is difficult to find statistics relating to pet abandonment in the UAE. There are many welfare groups and individuals working hard to help abandoned and stray animals across the country however there is no single source or consolidation of this data for now.
Some welfare groups will indicate there could be upwards of 100,000 stray cats alone on the streets of Dubai. This seems like an overwhelming issue to tackle, but that doesn’t slow down the dozens upon dozens of amazing people who continue to rescue, neuter, foster adopt and rehome these furbabies.
UK
The RSPCA in the UK also braces itself each summer as thousands of animals are dumped. One article from 2016 refers to pet owners abandoning their animals at a rate of 1 every hour because they want to go on holiday.
In 2015 over 9,000 pets were dumped across the UK.
The RSPCA provides advice on what to do before giving up an unwanted pet:

USA
The ASPCA (American Society for the Prevention of Cruelty to Animals) reports a range of statistics in relation to homeless animals and animals in shelters. At the moment, no government institution or animal organization is responsible for tabulating national statistics for the animal protection movement so the figures provided on their website are national estimates.
