Yorkie 8 months diarrhea

Hello!😘

We have a 8months old Yorkie boy who is having recurrent diarrhea since last month. He does poop so many times a day when he is in flare, more than 10-15 times. His poop is like mushy and has a looot of mucus.

The first time he has Giardia and got treatment and gastro diet and everything went well.

Then the second and third time, the vet doctors told us that he has food allergy.He was eating N&D solid food with lamb. The doctors told us to go with Royal Canin Hypollergenic for a month. And we us Fortiflora as probiotics and Entero-chronic.

Do you have any tips or recommendations for us?😟😢 We really want him to get well and be able to enjoy his food.
