Mix the critical care and lactulose, then just using the syringe, stick the end in the corner of his mouth and just put a dab on his tongue...and just keep doing that... you CAN do it...Oh shoot! We almost did that today but I chickened out of trying to make him swallow anything...Thank you maggie! My friend will be back tomorrow and I will have it mixed up and ready to go. I am not very confident doing anything intrusive to him by myself yet. But I will soon be. Funny, you would think about 28 years of having him I would be able to do this stuff. He has been so darn healthy til now
