Being new to retrievers, we've been searching the internet and asking friends about suitable games for our 10 week old pup, which has actually led to confusion. We tried playing ball, but someone told us that teaching them to chase / catch a tennis ball is dangerous as there are many cases that they can be swallowed and get stuck in their throats... an emergency situation requiring the prompt attention of a vet. The other toy we got was a tug of war rope, which he enjoys, but further advice has been that this puts the pup in an adversarial state with you, which should be avoided, and you need to make sure you win or he will think he's the pack leader... also a good reason to avoid. Seems like the games he likes always have some unwanted side-effect. Any advice on suitable and fun games?
