Is there any fix to my pup retrieving the dummy by the rope. will this fix when i get to force fetching

Take the rope off till older.JMO

absolutely agree with Dan. Simple solution

I agree with everybody remove the rope also on a very young dog use small bumpers with or without a pigeon wing tied at both ends of the bumper, nothing that flops around just my 2cts. worth. One more thing I never run a very young pup on land without a long line on, you have more control over pup. This also depends on pups age.
