Hi there! Well, for me I just switch Scottie straight away. Meaning today's meal is kibble...tomorrow is full raw

He took to it very well, and had no problems at all

It's best to switch cold turkey, because mixing kibbles and raw is not that feasible.
In the beginning of a raw meal, your dog might not be used to it. When Scottie had his first meal, he looked at me like I just gave him some weird thing to eat, but after he chewed on it, he liked it and we never looked back since then

If your dog hasn't gotten used to eating, you could cut lines into the meat to make it easier for her to bite onto the meat and tear it off

Some people also use strong smelling food like cheese to make the raw meat more palatable, but I think you should let her try the meat as it is first before doing that. If she really doesn't want to eat, you could try that.

ok i will try that...coz i tried many medication to relive her itchyness and just doesn't work..hopefully by giving her barf diet she gets all better..thanks for the info
