I've seen a 9 yr F(S) Cairn Terrier that has been dragging the LF toes for the past 5 weeks. Foot will also slide out from under her sometimes when walking.The problem began following a routine dentistry and grooming. Owner wonders if wasn't happening on/off before that. No known trauma. Nothing obvious on Xray. No improvement with Metacam.There is pronounced muscle atrophy over the left scapula/ shoulder/triceps and while she drags her toes there is a fairly normal knuckling response. No obvious muscle spasm. She is a nervous anxious dog and has been shrieking when the other dogs in the household approach her or bump into her. She is moderately sensitive on palpation of GB-20, 21, BL-10,11, GV-14 and BL-18,19. Reduced range of motion of the neck laterally L>R, and somewhat on extension of the neck.Good appetite, no digestive or skin issues, thunderphobic. No notable difference in lameness with different weather or after rest. Feet are cool.Tongue sl. pale with a thin white coat. Pulse moderate to deep, sl weak, a bit wiry improved with needling GB points. I have acupunctured her twice with no improvement except she hasn't been shrieking at the other dogs approaching her or her being picked up. Points used have been GB 20,21, BL-10,11, GV-14, TH-5, LI-10, SI-3,GB-34, BL-19. I started her on Benefit Hips and Knees and DHJST. She's only had a few days on the herbs. I wondered about adding Bu Gan Tang, despite the lack of obvious muscle spasm . Considering XHLD but the dog tends toward warm not cool and while seems to need Blood moved to the periphery there looks to be Blood deficiency. The owner hasn't been able to go for the chiro assessment yet. Any thoughts you might have would be appreciated. Many thanks, Llewanda
