There are problems involving getting another dog.
The first problem is, my son has been diagnosed with Trigeminal Neuralgia. He's been in severe facial pain, and almost any noise sets it off. Dog barking included. :-(
Then there's the age problem. I'm not that young, in fact in a few years I'll get all the trappings of Medicare and Social Security. I have fibromyalgia and arthritis. I can't help but worry if I'm up to the commitment of dog ownership.
I do miss not having a dog. Pepper, like Kate, Juliana and Freckles, were such a comfort when I needed it, and companionship when I was alone. I feel like there is a dog-shaped hole in my heart. It only gets worse when I look at Petfinder. (headdesk)
