If you notice something isn’t quite right with the dog’s chin, make a mental note of which side was swollen first. This helps the vet figure out which gland is damaged. If in doubt as to which side is affected, stand directly in front of the dog and compare one side with the other to see which is more swollen. The swelling will probably feel a bit squishy when you press it, like a fluid-filled balloon.
To check for swellings under the tongue, watch the dog very carefully when she yawns. Alternatively, open her mouth and gently move the tongue to one side so that you can get a look underneath.
She may also have trouble chewing on toys.
This is why it’s important to know which side the swelling started on. A vet will need to know which side the infected gland is on so she can remove it. Sometimes, if the swelling is under the tongue, the salivary glands under the tongue can be removed, but this can be demanding. Instead, many surgeons favor marsupialization of the swelling. This means they make an incision into the lump to let it drain out, then suture the edges to the tongue so that the lump stays permanently open and saliva cannot build up again. Instead, it drains into the mouth.
