I have an 8 year old Schnauzer mix female, 10.5 lbs. My question is she has horrible breath. We have other small dogs that do not have this problem. Is this a health issue that should be diagnosed by a dr.?

How adorable! Often bad breat is related to dental disease. There may be gingivitis or she may have a tooth infection. Many times the teeth may look alright but a deeper exam under anesthesia often shows some problems. I recommend a dental exam by your veterinarian. If there is tartar or gum disease they will recommend a dental cleaning. Many veterinarians now take dental X-ray also to see pockets of infection around the tooth roots. After the teeth are cleaned then I recommend brushing the teeth or using an antibacterial mouth rinse. Small dogs tend to have more dental problems probably due to their smaller mouths compared to a big dog. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Lela.
