I have an 11 year old female lab. In good health, fit, eating and exercising/sleeping all as normal. Over the summer the PILs lost her Furminator, so not been brushed for a few weeks. However lots of swimming and towelling, so loose fur been largely maintained that way.
Found the furminator the other day, so this week back into routine of regular brushing. However, the second I touch her with it, she is all twitchy and ticklish - legs going like the clappers etc. Doesn't seem painful, and she is not resisting it but involuntary action on her part.
Have inspected carefully and other than a small amount of dry skin (normal for her) I can't see any evidence of sores, bites, fleas etc. To my knowledge she has never had fleas or other infestations, but I am assuming if something were on her, there would be scratches, bites or other evidence.
Grateful for any tips on whether I should investigate further, or perhaps just part of her getting older and a few weeks without brushing means I've really noticed this change in her this week.
TIA.
