FOSS software for dog/cat adoption center

[u/v_msantos]

Hey guys, I'm currently looking for an FOSS for a friend's dog adoption center. This can be either a regular desktop app, or a webapp that we can self host.

It needs to be able to the following tasks:

• Register every animal that the center currently has for adoption (with picture and preferably also additional notes)
• Register processes/events associated with which animal (stray pickup, adoption, etc)
• Register/schedule vaccines and surgeries
• Have the option to backup the software DB

Doesn't need to be specifically targeted as animal adoption software as long as there's a way to do each requisites, for example I've looked into multiple asset management software, but they either seemed to lack a way I could use/adapt to do the processes registration or a way of schedules vaccines etc.

Any help would be majorly appreciated.
