Hi again,Thank you for your patience. Bo's diarrhea and firm abdomen are definitely a concern here and there are a few things that could be causing these symptoms in your boy. We need to consider a range of possible issues here including anything from an oncoming infectious gastroenteritis, to intestinal parasites, to a toxicity, to an internal organ problem, or even an ingestion of a heap of the wild cherries from your backyard. The cherries themselves aren't toxic
per se, but they could cause gastrointestinal symptoms like you are seeing - so this is a definitive possibility. You are definitely going to need to continue to keep a close eye
on Bo. For now, you can with hold his food until the morning, but make sure he has plenty of fresh water available and do encourage him to drink. If he won't drink, or starts vomiting, then you will need to get him seen tonight as he could quickly become dehydrated. From tomorrow morning, you can start him on a bland diet of cooked, boneless, skinless chicken
breast and boiled white rice. Also make sure Bo is up to date with his deworming tablets over the next few days. For now, please keep a close eye on his mucus membranes, capillary refill time and respiratory rate as follows:Mucus membranes - flip his lip and look at the color of his gums. They should maintain a nice salmon pink color. Get him to the emergency Vet if they appear white or very pale pink, or if they are a dark deep red color.Capillary Refill time - this measures blood perfusion and test this by putting your thumb on his gum to apply pressure. After you release your thumb you will see the gum blanch. Capillary refill time is the amount of time it takes (in seconds) for the gum to return to a healthy pink color from the blanched white color. If 2 seconds or less don't worry - if it is taking significantly more time, again - off to the emergency Vet.Respiratory Rate - if he is continuously panting throughout the night, this is a sign of shock and or pain and a signal for a trip to the emergency Vet. For now, you may also want to try him with a little pepcid. The typical dose for this type of situation is 0.25mg per pound of body weight up to twice daily. You can read more about the use of Pepcid in dogs online here: http://www.petplace.com/article/drug-library/library/over-the-counter/famotidine
-pepcidBest of luck with Bo hopefully these symptoms settle soon. If he is quite lethargic now, or seems bloated, then you are best off getting him seen straight away.
