How to train her to stop whining? Advice pls:/

My mom’s (1yro) basset hound whines almost all the time. No matter how many walks she gets and how much attention she has already received or not received.

My mom is not very good at consistent raising the animal (our everyday life has been very chaotic lately and my mom is tired, which means she often says that she “doesn’t have the energy to manage her whining dog right now, shell grow out of it”).

I dont think she’ll grow out of the whining without learning it…any tips? i will do my best to help out and share any advice with my mom. thank you!
