Welcome...I'm not understanding this.....I sure don't understand the catheter part....Did you say that was routine? That doesn't make sense.....Or the pulling your dog from the dental.....Would you please come back and explain again?
I'm hoping we can help you & your guy.........Thanks,Karla
P.S. How old is this guy and what breed? What did the rest of his bloodwork look like? Anything else???
I do so understand how worried you must be. And added to that, it's always horrid when they are in hospital, even for a short time, I know.
What was the initial reason he had a catheter inserted "to check for blockages in the penis"?
When he had his bloodwork -were there any abnormal values anywhere? Did the vet go through the results with you? How for instance was his liver function? Does he have any signs of infection? What's his white blood cell count?
Your vet will have to run a few tests to get to the bottom of why his platelet count is low. There could be a number of different reasons. It is possible for your dog to receive a platelet transfusion if necessary, to help his situation, but the cause for this in the first place will have to be found and treated.
I hope he will be OK. I am sure the best place for him right now is at the vet's where they can monitor his condition. Good luck and I hope things will work out well for him.
