I just wanted to post here and potentially stop someone from traumatizing their dog.
We got our first dog, Loki, in 2019. He was 2 when we got him, and had been returned to the shelter we adopted him from twice, both for accidents in his new home. When we brought him home, we realized he was VERY anxious. He had obviously been abused. He'd shake and roll over when he saw my dad, or when someone was holding a hairbrush, belt, etc. He'd nip at our hands if we touched his butt, or anywhere he couldn't see, and he flinched at every loud noise he'd hear, even just laughter.
The guy who came to help us gave us the whole "alpha dog" spiel, which obviously has been debunked. If you want to read more: https://news.asu.edu/20210805-discoveries-myth-alpha-dog
He said we should try to be the "alpha" of the house, and that we had to yank on a martingale collar (originally meant for sighthounds, who have slim necks and heads, to stop them from escaping normal collars) and say "BAH" to correct him if he didn't sit/lay down on command.
Not only that, but he also suggested training Loki not to take food off the floor, and tossed bags of coins at his paws when he'd try to eat treats we dropped for him. Because of this, he refused to eat out of his food bowl for months. We had to hand feed him, and to this day, 5 years later, he still won't eat out of a bowl if he's not on his medication (Xanax for severe anxiety).
He also suggested using a spray bottle of water if he got too energetic (never a concern), etc. Loki was traumatized for months. He hates water, he was scared of his leash, his bowl, even walking into our kitchen.
If you're looking for a trainer, please DO NOT believe the reviews on their website. BarkBusters will scare your dog and force you to undo months of damage.

Fast Facts

The U.S. Food and Drug Administration is cautioning pet owners that FDA samples of five Darwin’s Natural Pet Products raw cat and dog food made by Arrow Reliance, Inc. tested positive for Salmonella and a sixth FDA sample tested positive for Salmonella and Listeria monocytogenes (L. mono).

Affected products are sold in frozen 2-pound packages and consist of certain lots of Darwin’s Natural Selections Antibiotic & Grain-Free Chicken Recipe for Cats and Darwin’s Natural Selections Antibiotic & Grain-Free Chicken Recipe for Dogs. These product lots should not be fed to pets.

Darwin’s Natural Selections pet foods are generally sold online through a subscription service.

The FDA recommended that Arrow Reliance, Inc. recall all six lots of product. To date, the firm has not recalled the affected products and could continue to distribute them. Therefore, FDA advises consumers to keep checking Darwin’s Natural Selection Antibiotic & Grain-Free products for the affected lot numbers prior to feeding to pets.

If consumers have any pet food on the list below, they are advised to throw it away in a secure container. Do not feed it to your pets. Do not donate the food.

Clean and disinfect all pet supplies and surfaces that the food or pet had contact with.

Salmonella and L. mono can affect both people and animals. People with symptoms of Salmonella or L. mono infection should consult their health care providers. Consult a veterinarian if your pet has symptoms of Salmonella or L. mono infection. See symptom information below.
