Thanks for the answer to my question.
Unfortunately, my state board prohibits phone conversations but I hope that this format continues to be acceptable to you. My apologies for the inconvenience.
I can just imagine how uncomfortable her foot must be after such an incident. And, these small dogs do tend to react more strongly than larger dogs which could account for her behavior. I do have a few suggestions which may help.
1. I'd soak her foot in a warm Epsom Salt bath for 10-15 minutes; you could repeat this twice a day, if necessary.
2. Since she's not taking any medication, then otc Aspirin can be given at a dose of 1/2-1 low dose (81 mg) tablet twice a day, with food to avoid stomach upset. The anti-inflammatory as well as anti-pain properties may be of benefit in this situation.
3. If the foot is a little swollen, then otc Benadryl can be given at a dose of 1/4th of a 25 mg tablet twice a day; sedation can be seen as a side effect, though.
If she continues to act uncomfortable, then a vet visit tomorrow may be wise.
I hope this helps, Deb
