My 5 mth old chihuahua/yorkie puppy was in her crate and somehow got her collar into her mouth, when my husband got home from work he got her out and noticed it and in the process of getting collar off a tooth from the back was broken off. She is acting normal except shaking her head acting like her ear is bothering her. she has even ate food since it happened bbut the tooth looks like only part of root came out. I have RXV clinda guard, equivalent to 25mg per ml clindamyacin. I have had it about 1 yr from my other dog. Would it help her? How much? And what signs should I look for to take her into vet.
