I just had this today. After our walk Rox started to act weird all of a sudden: panting, pacing, constantly stretching and bowing. She didn't want breakfast and even turned down a piece of cheese, which she usually loves. OH is interstate and I had to go to work. Luckily I'm self employed and had only one appointment, which I could postpone to another day. So I decided to work from home today to keep an eye on her and take her to the vet if she gets worse.
But this isn't always possible and if I was employed I had to make the choice to call in sick or leave the dog alone. She seems to have settled down a little by now and we may get away without a trip to the vet. But still, I really don't like leaving a distressed dog alone at home. What do you do in such a situation?
