Important notes: 1. HE seems completely happy And playful. 2. HE eats normaly And has appetite. 3. I messured his body temperature its 38.4 celsius. 4. Today he popped 2 times normaly without ant diarrhea. 5. Yesterday He had Veru stressful day. Why did HE get this diarrhea? Do i rush him to vet?

I am sorry to hear about your dog! It sounds like he is doing well and just had one bout of diarrhea. It is possible he had diarrhea as a result of stress (we can see something called stress colitis). It is possible the grass or something else he ate outdoors could have caused an upset stomach. If your dog is energetic, eating, not vomiting, and the diarrhea does not have blood, then you can try just observing him for a day or two as long as he isn't having repeated bouts of diarrhea. You can try feeding a bland diet of plain cooked white rice and shredded boiled chicken breast or lean ground beef with the fat drained off. We want something simple and bland. You also may be able to find probiotics at the pet store (I am not sure if they are available where you live) that can be helpful. If the diarrhea continues, or your dog becomes lethargic or starts vomiting/stops eating then a vet exam would be recommended to check for things like parasites and infection.
