How exciting.hope to see pictures. Ive used ceramic bowls from puppyhood. Considering beagles are almost fully grown at about 6 months I dont think you have to be overly concerned about a type. Ceramic, i believe , is best for cleaning.
I prefer stainless steel bowls made for dogs with long ears; Ally McBeagle was a messy drinker and before the narrow bowls, her ears would get sopping wet. They come in puppy and adult versions; got mine at a local pet store. I got her at 11 weeks, and wither height was about 5 inches. She was all ears and paws.🐾
