I discussed this with Frenchy last night over a glass of wine.
. She also suggested kibble saturated in water.
The Merrick is large clumpy, meaty food. She has absolutely no problem with eating it as it is moist and easy to lick up onto her tongue.
I watched her eat a wellness training treat which is like beef jerky but soft. I can see that she has difficulty with that even with the teeth she has. I truly believe that she is in pain when she eats. Heck if I remember loose teeth and trying to eat, it was not pleasant. I am certain she is feeling the same way I did wayyyyyyyyyyyy back then.
