It's good that you ignore her, when you don't like her behavior. Do you leash her in the house? If you leash them and let them drag the leash, you have something to grab to get them under control.
I know I throw a lot of stuff out there. The thing is, every dog is different. One thing doesn't work for every dog. It's all about finding what works with your dog. I am confident that you will find what works for Molly. Cassie is 11 and Boh will be 11 in June. So - Joann and I haven't had pups in awhile either. LOL! The dog I lost in November was 8, so even her puppy years were some time ago.
Only other advice.... a tired puppy is a good puppy. They are super smart, so work her brain. It will help to drain her excess energy. Do this by upping her obedience training, puzzle games and working her nose. You can buy puzzles, or make your own. It is as simple as putting some kibble in an empty water bottle and having her figure out how to get it out. Hold a treat in one hand. Make fists and have her tell you which hand. Start making it harder. Hide some treats for her to find. My husband brought a bunch of boxes home for me to pack up my books. I put a few pieces of kibble in one box. I randomly stacked them up. Boh had to find the right box, open it and retrieve the treats. It's really fun to watch them do what they were bred to do.
I promise Molly will get better. She won't be a puppy forever. 💕
I leash her in the house - she chews them in objection (even the metal part). I'm on the 3rd leash. When I try to control her with the leash, she rolls around like an alligator! She pulls hard on it if I am not holding it (e.g., sitting on it - I made the mistake of wrapping the handle around my ankle, so I could watch TV, not good. I have her confined to whatever room we are in so she can't freely roam the house. When I'm not holding the lease, she is too fast for me to grab it. Every day - 3 obedience sessions - she gets bored or has a short attention span - even with treats. She also does the limp dog routine. I have two puzzle games for her, she mastered the puppy hide n' slide (we play with it anyway, she's done in minute finding the kibble and we do it several times. Have a ball that's flat on one side and distributes treats, that keeps her interest for about 5 min. I bought a bigger kong, she destroyed the puppy one. Have a snuffle mat, again 5 min depending on how much kibble I want her to eat but she will also pull at the fabric and eat it. Boxes are chew toys. She swallows what she bites off - Ally McBeagle would chew but she would spit it out. I had to take all stuffed toys away. I have to be careful with the amount of kibble, she throws it up if she's active. We also play pick the hand that has the kibble. On advice of vet, I feed her 4x a day, twice in am and twice in pm about an hour apart. I looked up a bunch of game on the internet and we play them.
On walks - picks up everything - sticks, mulch, grass bits, dead worms, leaves (we walk on a paved sidewalk). I walk her with a harness. I tried a halti and didn't like the way it came up toward her eyes, even though it's a puppy. Yesterday after our afternoon walk, she threw up grass and mulch (at least she threw it up). I pull at least 12-13 items our of her mouth on a short walk to the point where now she's clamping her mouth closed or gulping it down.
It's just good to be able to share this because I know everyone has gone through it - therapy for me in typing it, lol.
We met a lovely a chocolate lab, Cocoa, on our walks - she's 1.5 yrs old, the hugest lab I've ever seen and still a playful puppy. Molly goes bonkers for her, I can barely restrain her. Her owner is very nice and knowledgeable and we let them greet, Molly tries to jump at her face. Cocoa takes for a bit and then she gives her a sound (not really a growl but clearly telling her to stop that behavior and Molly doesn't respect it). Yesterday he extended an invitation for them to play in their fenced backyard. We've kept the interactions short enough so Cocoa doesn't get riled up. I'm a bit hesitant because I'm afraid Molly will push Cocoa to her limit. I can't let people greet her because of the jumping and biting. We'll start group puppy class and if that doesn't help then I'm getting a 1:1 trainer. I'm sure there's something I'm not doing correctly that is kicking off this behavior.
Thanks for all your suggestions!!! 🐶
