Ok, I have searched the threads on edible chews. Nothing really convincing.
My almost 1 yr. male yorkie 6.6 lbs. chews everything to pieces. Toys last about 1 hour. He chews the the squeakers right out. He chews ropes into strings. I mean everything. I have to pull stuff out of his mouth constantly. Thank goodness he never chews furniture or tables, etc.
Just bought a twin pack of bacon flavored Nyla bone edibles, but haven't opened them yet.
These things really scare me with yorkie. I never give him chew toys unless I watch him.
But, anyone think these are bad & harmful?
I need help on what he can chew @ ingest & lasts longer than a minute.
Thanks to all that will reply with knowledge.
