Thank you for this. Poor Rudy doesn't have many toys. He had a plushie that a neighbour gave him. It lasted 22 seconds. He had a tuggy thing, I threw it out because it seemed it was starting to fall apart and I was scared he'd eat the strings. He does have a blue plastic Kong long squeaky chew thing that he loves. It's the only thing he hasn't been able to shred to pieces. Rudy's 102 pounds of destruction! Luckily, 3 hours of outdoor play seems to keep him happy without toys.
As for treats, he likes the odd Milkbone and loves PureBites.
Thank you for your advice, I look forward to it to make sure I'm doing the right thing. You save me a lot of trouble sorting through research.
