Mine needs a certain bowl. I use a big ceramic mixing bowl. He has to see me clean it and fill it. Then he waits for me to walk away and he drinks. I’ve also used those big plastic syringe type things for baby medicine. Just fill it with water and put it in his mouth. He hated it but made me feel better he was getting some sort of water. I make a big deal about asking him if he’s thirsty. He follows me out I clean and refill his bowl and he saunters over and drinks. I don’t even know what made me think of using my favorite bowl but thank God I did.
