Hi Manu! You might want to call the vet and let them know that he is reacting this way to the Buprex When Bubba had his last dental, the general anesthesia they used did that to him. Every time I woke up he was on my bed staring at me........ It was very alarming.
I am glad he is eating for you. But he does need to sleep too.
I do not have advice but any vines your way
I hope Porto is able to sleep soon. Anesthesia did that to my Shmee too like Bubba, but I do not have experience with bupre. I wish you luck on your dental search too, my vet told me my Shmee had gingivitis and might need a few teeth out. After an X-ray, they found he needed SEVEN extractions! I couldn't believe it. Glad Porto is eating, I hope he continues to eat today.
Those hugs x 10 times back for you and Olive! Thank you, all of you incredible people!
