another night of franky being sick

Franky looks healthy-
Runs about the garden playing with our other staffie Lucy,
Eats dried dog food (orijen)
Water is always renewed 3-4 times a day.
Motions are OK

He is being sick 2-3 times a week mainly at night. Sometimes it is just liquid but the majority of times it is undigested food. He will then continue licking his lips none stop for a while before going back to sleep again.

Inflimation of the stomach comes to mind and even bloating-- is there a chance it is because he is rushing his food or may be a raised food container would be benefitial in helping him digest food.

how often do you feed him?

Half his dried food is measured out and put onto the floor in the morning, then the same amount is given between 5-6 in the evening. He never eats it all up, but prefers to just go backwards and forwards.
He drinks plenty of water and I'm now wondering if he is gulping a lot of air in at the same time?
With my last 2 dogs I raised their food up on stands and was thinking that this may be a salution.

i would seek vet advice seems like suddenly his stomach can't tolerate the food and perhaps developed an allergy id record exactly when your dog s being sick and how often and what the sick consists of this way the vet can give a proper diagnosis as to what the problem is and the best way forward. good luck.

Thank you Mia05
I will deff keep a diary on his wellbeing and write down every detail on time/date and sickness. It is now 2 days since he was last sick (his weight hasn't altered)
Franky's booster injection is due in 2-3 weeks so if he seems ok health-wise I will wait and bring the subject up then.
