I have a female G - Page 1

It could be pano,  however, if it continues I would go ahead and have her shoulders/elbows xrayed.  Pano will also show up on xray, but not right away. 

First I thought pannus, but the vet would have picked up on that. When you mentioned knucking under of the toes, I think it HAS to be neurological. That's called proprioreceptor deficit, and my first GSD had it when arthritis destroyed her spine to the point the nerve signals weren't getting through to her hind legs.

Let's hope it's temporay, and due to an injury, and will resolve with the help of the metacam. I hate to think what else might be causing it....   Could be pressure on a nerve from a tumor.

What is knuckling?

Sunsilver, I have googled that disease and cannot find anything on it, does it have another name?

 I googled and read up on Pano, that is a possibility, her first heat, change in food to a higher protien, addition of catfood ( not previously used) higher protien. sheeeesh lets just hope its nothing more than a twisted ankle while playing ball. I have always kept her exercise minimal, no jumping, no extended running, limited ball chasing; because I did not want to chance HD or other injuries.

to me knuckling is the involuntary turning under of the toes or foot at the ankle or knee.

Shandra, propriorreceptor deficit isn't a disease. It just describes what is happening with your dog. Proprioreceptors are the nerve cells that tell the dog what position a particular body part is in. When they aren't working properly (have a deficit) the dog doesn't realize its toes are turned under, and won't make the effort to straighten them out. It's a symptom, not a disease in itself.

The dog is vaccinated, right? Distemper can cause neurological symptoms.

No xrays, huh?? Would have been my first thought since this has been going on for a week, I think......

It is not unusual at all for a dog to not put any weight on a pano affected limb such as the front leg when still.. it's a very typical symptom in my experience..

However, it is pretty easy to determine with a physical exam, pressure applied to the bone will usually cause a reaction in the dog ....

One suggestion.. get her off Puppy food, put her on a decent adult food if you can't or choose not to feed raw.. BTW, 6 cups of food is an enormous amount of food! If she is really that large, I would keep her very very lean ......

Also, cat food is for cats and I think I have heard if fed over time is not appropriate for dogs as dog food is not appropriate for cats.. there are plenty of  decent canned dog foods...... 

I hope this helps

Oops...PANO, short for panosteitis, not pannus!  That's what I meant to say in my first post.  Pannus is an eye disease! Sorry, it was late at night...

Dkiah, my female was on 6 cups of food a day at the same age, and barely maintaining a decent weight! If there's one thing I've discovered with her, it's just how different dogs are in their food requirements!  Now she's past her first heat (which made a HUGE difference!) she's only getting about 3 1/2 cups!
