While Lilia's pet is still an egg so it could not participate in any fight she put it in Stephanie's Underwater house to incubate since it would only hatch in a water environment
For Herish pet it do not do anything other than lazing about in the garden so Teeth found no reason to fight her
There are only three pets that proved to be a challenge to Teeth it was Browny, Chinbu and Light
Chinbu was Terris pet Earth Bear
Browny was Big Bear pet Brown Bear
and Light was Star's pet Star Beast
Big Bear would always bring Browny every time he train and work because Browny considered Big Bear his father he would help him in his work and would also work out if Big Bear also work out
If Teeth do not have such a great defence he would definitely lose to Browny but because he would always be beaten by Bun Bun and slashed by Purple Kitty his skin become extremely tough
