daughter dog aggressively barking at mother dog
my dog is 17 years old, we kept a female pup from her litter about 8 years ago. for the last 3 weeks, she has been aggressively barking at her mom. At first we thought she was getting possessive with the food. But she is doing it at odd times. Mommy dog walking into room, she will bark, laying down beside her, she will bark/growl, laying in the backyard sleeping, she will do it. It's the kind of mean, dog comes into yard attack barking. Any & all help would be great.
