My dog is lethargic, has stiff legs, and mouth ulcers. Any ideas?

Question

My dog has been acting sick for a couple of days now. It started as him being lethargic and slowly his back legs started to give him problems and he started walking stiffly on them. He is not painful in his legs or down his back. He vomited the first night we noticed him being sick and hasn't since then. He has developed what look like ulcers in his lip and on the bottom of his tounge. I took him to the vet and he acted normal. They dewormed him and gave him flagyl, it isnt helping. Any ideas?

Thank you for submitting your question regarding Zeus. I would recommend having some bloodwork checked on him. Rarely, severe kidney disease can cause ulcers in the mouth. If this is not the case, he could be reluctant to move due to joint, muscle or abdominal pain. Unfortunately, his signs seen more complex than when he was originally evaluated so it is worth having seen again. Good luck!
