Good day- We are the proud owners of a one-year-old English Pointer named Bruno and a proud patient of Dr. Magnifico’s. Recently, Bruno has been shaking his head more often and scratching his ears. He has also been sleeping much more the past few days. When not sleeping, he is still pretty playful and eating/drinking. How do you know if he has an ear infection or not? His ears have been professional cleaned, but same actions with his head. Also, no smells coming from his ears. Any suggestions? Thank you.
