It'll help if your dog becomes more interested in toys,..
To increase her interest in toys, have you ever tried rubbing cheese, or maybe peanut butter, onto the toys? That did the trick for my dog. Buddy is toy-crazy NOW.
My dog tends to get bored with some toys, if he's had them for a long long time. (so we swap out groups of toys, and hide ones he's bored with for a while.) He LOVES, adores, NEW toys. Does you dog show any interest in NEW toys?
Dogs tend to like NEW toys they've never seen before. We get ours at Goodwill, only 25 cents to get toys there.
Does he like squeak toys at all? Many dogs seem interested in squeak toys.
Ha, id think a "clicker" might help with teaching your dog to fetch. Are you familiar with clicker training?
NOt sure about the "hold", you mean, to hold it in her mouth to bring it back to you? Is that what you mean?
My dog is no retriever, either, doesn't much show interest in retrieving stuff to me, more than about 3 times.
STand by, i'm sure some smarter people more experienced will be along shortly!! Ha ha!
