Sorry, your doggie is ill. I hope she will feel better soon.
As Avlady says, yes yes and yes. You can feel this for a pet. People love a lot their dogs. Pets as dogs or cats have a quiet developed brain, and they interact with us with a great ability.
A dog is like another member of the family.
I understand that in your case, you being alone, the conection, the affection is even stronger.

I remember when I were alone and isolated at home, my careless and affection for my pets was very strong and I hadn't a dog or a cat, I had a duck or a bird. I had nothing else or noone else to express my affection with.

Look at my avatar. They are Perla and Miky. I love them so badly. They are my joy, my friends, my kids.

Anyway, you realized that you are alone. So, it maybe time for you to look for human friends as well. I wish you luck for you and your doggie.
