I bought something this week that has revolutionized my relationship with Bailey, which was speeding downhill at a breakneck speed. Come to find out, most labradoodles are known for their high energy levels. She is also hyper, spazzy, quick to bark for attention, and known to eat food off of the dinner table and counters. Lest I convey the wrong impression, I should list her attributes too. She's gentle and protective with the kids, very loving, house-broken, and incredibly smart. It's just that the negative things about her have been driving me so crazy, I couldn't really enjoy the good things about her.
Finally... I bought a "gentle leader". It's a painless harness that snaps behind her ears and loops up around her snout. The two loops connect underneath her throat, with a short strip that connects easily to a leash.
The result is amazing. She doesn't yank me down the block or pull me down the front stairs on her walks and she hardly barks anymore. It's like the difference between a horse with or without it's bridle. She's focused, calmed, and submissive, at least most of the time.
