Get Your Dog Care Questions Answered by Experts
Hi. My name is***** Thank you for your question. Interesting. I'm going to be honest here and say that medically there shouldn't be anything that would cause this type of vomiting schedule. To be honest, the most common cause of infrequent vomiting and diarrhea like this is something that he's eating / getting that he's having a reaction too. Could he be reacting to a monthly flea or heart worm preventative? That is something that happens pretty much on that schedule you are saying. If it isn't this, then is he finding something that just "rocks" his gut for that period of time and then he gets over it. I know you say your eliminating food / treats / etc., but could he be still finding something? Something outside? Mushrooms?
Is he on a monthly heartworm preventative? That is good that he's got that controlled of an environment. Good thought on the delivery situation with a treat being given at that time. Any chance some other guest is coming that could be giving him something?
I wouldn't be overly worried about this as long as it is that infrequent, he's recovering nicely from it, he's otherwise eating / drinking / playing normally, he's not losing weight, etc... My guess is again he's finding something to cause this. Medically I can't think of anything that would fit this.
