No tick exposure but I am wondering if my mastiff didn't step on him when we were in the car, seems to be as of Friday this started. I took him for a walk no realizing he had a issue and we were standing in dirt and it was like he had no grip and just fell to the ground but he hasn't fell since then. i noticed today a couple times it looked like his "toes" were dragging but he did that once on the carpet but hasn't done that again. He is still acting normal still jumping up on the couch
What you're describing sounds like a proprioception deficit, which is not uncommon in giant breed geriatric dogs who have some degenerative issues rather than an acute trauma (such as being stepped on). Granted, this absolutely could have been exacerbated by your other dog accidentally stepping on him.
You can find more information here: http://www.petplace.com/dogs/proprioceptive-deficits-in-dogs/page1.aspx
The fact that his proprioception is off (where his feet are in space, which explains why he drags that foot) is always a key sign that there's something going on in his head or with the nerves to that parts of the body.
I think that if this were my dog, I really do think that the next step would be an x-ray to rule out things like bulging discs or spondylosis (a gradual narrowing of the spine that can compress the spinal cord which causes a misfiring of signals to the limbs). Unfortunately in St. Bernards, because they're so big and have such a long back, it's often where we find the problems.
If that comes back clear, then you may want to ask for a referral to a veterinary neurologist. These are the guys who deal with nerve issues day in and day out, and will be the most likely to figure out what is going on with your boy.
I hope this helps.
Is this going to be something that is going to effect more than the one leg? I mean I love him to pieces but he will be 11 in Dec so we aren't talking about a young dog
seems like the rymadyl does help the leg I was concerned more cause its warm to the touch in that area its just above the foot
I don't think I mentioned that it is a bit swollen as well, sorry I am trying to tell you all but I am just so worried and can't get into vet till next week. He would kind of jump if u touched it but as of now he will allow you to rub and touch it today
Ok thanks so much I will keep with Rymadyl and try and limit him, take him to the vet next week and have it looked at then. Thanks for the help
