Just as the title said: when would you consider baby teeth to be "retained" and require vet help?
Our puppy has double upper canines for a couple weeks now. The adult canines are half way in. The babies are stuck in really good, and don't look like they're going anywhere... But she is just 6 months old. All her other teeth are done, I think.
So would you wait it out? Does it take a while for the upper canines to fall out sometimes?
She is our first baby small dog.
