Okay I was up ALL NIGHT with Diggy. I think its definately the revolution he is reacting to. I call the vet and they see very few reaction to Revolution vs Frontline so she didnt know what to tell me besides give hinm 1/2 tspn of childrens benedry. There are 3 vets at my vet office and Dr. Rob the owner who sees Bella 90% of the time is coming in at 2:00. What would you do, hold off on the benedryl til Dr Rob sees him or give it to him and if he stops reacting not take him in? Hubby is home with him right now Im at work. I hate this I get so freaked out over my babies. please tell me what you would do...Im trying to function and make decisions on 2 hours sleep and its not going so well.....
