My 7 month old retriver puppy has real behavior issues I cant seem to break. I cant afford a dog trainer since everyone I’ve contacted wants atleast $500 for 5 hours of basic training. The problems: she pulls on the leash…hard. she is constantly chewing on stuff. Anything in the floor. As soon as i turn my back shes into something… the trash, litter box, cat food, chasing the cats… she knows it wrong because when she sees me she looks down in shame. I have a prong collar for walking her, a shock collar for teaching her no. She’s smart and knows how to come, sit, lay, catch, drop it… However now she refuses to drop something she really wants. I cant give her chew bones or long lasting treats because she’s started growling and snaps at my kids when they come near her with it. I have a crate, that I put her in when she being bad. She refuses to calm down at all when there is something interesting like new people or another dog. I spend my entire day scolding her for doing bad things… so much to where I really dont want to be around her anymore. My kids hate her, and my husband is trying so hard to like her. Im at a complete loss as to how to train her to calm down and stop doing things she knows she isn’t supposed to do. I have a severe back injury and it is really hard for me to contain her when she’s acting a fool. Ive also tried having turkey in a treat pouch and only giving it to her when she’s being good. Which she will do till I run out then she’s right back at it. If anyone has any ideas please let me know.
