A FURsonal assistant
Dachshunds are a particularly intelligent dog breed that can help with a million and one different things. They can even perform service duties, though they’re not very common service dogs for obvious reasons (their size, for one). But the OP’s mother’s dachshund takes the cake in terms of how intelligent and empathetic a dachshund can be.
The OP’s mom would have fits of seizures from time to time. Eventually, the pet dachshund picked up on cues of an oncoming seizure and would frantically circle her while barking. Sadly, the dog suffered from epilepsy, but it had lived a full 17.5 years before passing into Doggy Heaven.
