Really, really like this one!
You probably have to connect the tablet to your computer, transfer the file(s), and then transfer from the computer to any external storage device like a USB thumb drive:

Have you tried the "silent mode"?

I see that your camera supports SD/SDHC/SDXC memory cards. If you do have the Mac Mini (2018 model?), it should have a SD card slot. Take the card out of the camera and insert it into the slot on the computer. A new folder will appear on your desktop. Follow these directions from Apple Support:
Import from a card reader or SD card
Some Mac computers have built-in SD card slots. If yours doesn’t, you can connect a device called a card reader that is compatible with your Mac and use it to import photos from a memory card, such as an SD or Compact Flash card.
Insert the card into your computer’s SD card slot, or connect a card reader to your computer and insert the card into the card reader.
In Photos, choose File > Import, then select the photos or videos you want and click Review for Import.
Note: If you participate in an iCloud Shared Photo Library, click the Library pop-up menu in the toolbar and choose the library to import into.
If you selected multiple photos or videos, do one of the following:
Import all new photos: Click Import All New Photos.
Import a selection of photos: Click the photos you want to import, then click Import Selected.
If a message asks whether you want to delete or keep the photos on your card after importing them, click Delete Items or Keep Items.
Photos then imports your photos and videos. To cancel importing, click Stop Import.
When all photos have been imported, eject the card from your computer or card reader.
Imported photos appear in the Imports and Photos albums in the sidebar.
Some card readers may not be compatible with Photos. For more information, check with the device’s manufacturer.
Good points! I have been involved with fostering rescued greyhounds since 2004. They are generally known to be docile, relaxed and very sociable with people; some are antsy around small kids. My group and other greyhound rescue groups have had to occasionally put down a dog because of biting and attacking kids/adults in the house, even after doing all we can to address this behavior (consultations with behavior specialists, anxiety medications, etc. . .) Fortunately, such drastic action is quite rare. My particular group avoids adopting dogs out to families with small children because of the risks. We made exceptions for those families that were very experienced and followed our instructions that we outlined in a signed document about kids and dogs. We specifically stated that dogs should NEVER BE ALLOWED ON THE SAME FURNITURE THAT KIDS USE! Some dogs are very possessive and do resource guarding, making them dangerous to be around small children that might grab the doggy toys, jump up on the same couch that the dog is being allowed to use, or disturbing the dog while he/she is sleeping. I guess it mostly comes down to the dog's personality/disposition and constant adult supervision whenever smaller kids are present.
