Seems to be "weaving" while standing

[MerlinsMom]

Merlin is a large Miniature Schnauzer. 18 months old and generally quite active. Just 2 weeks ago was neutered. Had to go to the vet as incision did not close properly due to his licking. He has been on antibiotics with an Elizabethan Collar to prevent the licking. No discharge is coming from incision site, but just today his normally cold, wet nose is dry and a little warm. When he looks up from a laying position or stands he appears to be kind of weaving like he is a little weak in the knees. He has been peeing and eating normally. He likes to dig and eats some weeds and grass in the yard. Could this all be due to this wierd eating habit or could it be alot more serious? He was just given to us and is a very good dog. I would hate to see him get sick. I did have a mixed breed in the past that had a siezure disorder and also wonder if this could be the case with our Merlin.

Thanks,
MM

Eating grass and weeds doesn't cause a dog to be weak in the legs, unless the grass has been treated with any kind of chemicals!

Are you sure the grass is safe? If so, I would take him back to the vet, as this kind of weaving is not normal.
