I have a 12 year old dog who is a little grouchy at times. these days things seem to bother her quicker then normal. is there anything I can give her or do for her to make her not so grouchy or to keep her from snapping at things
Dogs are very stoic animals and usually subtle changes in behaviour indicate something else going on. I highly recommend taking her in to your veterinarian for a thorough health check. It could be something as simple as arthritis which is bothering her so something more serious going on internally causing her pain. It could also be a behavioural issue at hand, again for which she will need medications.
Please do get her checked as soon as possible. I hope it is something that is easily fixed. All the best!
