I give our girls C.E.T. Enzymatic Oral Hygiene Chews and C.E.T. HEXtra Premium Chews with Chlorhexidine ,,
www.CEXDental.com,,,,the Petite size does great for my girls,, they LOVE them,, i offer them once a week or so,, but tear one strip to divide for them,, as they REALLY go to town on em,, when i had just Cricket alone,, she would eat on one for DAYS,, but Daisy INHALES everything,, so,, i have to part things out to them all now
and as for paper towel rolls,, toilet paper rolls,, they are dangerous to give to Parrots (we have 3) and yes,, the adhesive is dangerous for them,, so i'd not give them to my Yorkies either,, but dont KNOW of dangers for dogs with such
