Zesty Paws Wild Alaskan Salmon Oil is a well-rounded supplement designed to support the skin and coat health of both dogs and cats. Packed with Omega-3 fatty acids, including EPA and DHA, this product boosts the immune system, and aids in joint and heart function.

The supplement comes in an easy-to-use oil form, which makes it simple to mix with pet food without dealing with capsules. The pump dispenser ensures accurate dosing based on your pet's weight, making it convenient for pet owners to administer the right amount. The oil is sourced from Wild Alaskan Salmon, which is known for its high Omega-3 content, contributing to its purity and quality.

Potential buyers should note that the product's fishy smell might be off-putting to some pets and owners. Additionally, while it suits all life stages, it may require an adjustment period for pets not accustomed to fish oil in their diets. This supplement is ideal for pet owners looking for an easy-to-administer product that significantly benefits their pets' skin, coat, and health.

The Omega 3 Fish Oil for Dogs by GOODGROWLIES offers a comprehensive solution for various skin and coat problems in dogs. These chews are designed to deliver relief from dry and itchy skin, which is particularly beneficial for dogs suffering from allergies. The supplement contains Omega-3 fatty acids, including DHA and EPA, sourced from natural salmon oil, which promotes heart, hip, and joint health, making it suitable for both senior and active dogs.

The product comes in chew form, which makes it more palatable and easy to administer compared to pills or tablets. Additionally, the item is made in the USA, ensuring a level of quality and reliability. The 90-day satisfaction guarantee is a notable plus, providing a risk-free trial for pet owners.

However, it is worth noting that the chews are flavored with chicken, which might not be suitable for dogs with specific dietary restrictions or allergies to poultry. The dosage varies significantly based on the dog's weight, which could be inconvenient for households with multiple dogs of different sizes, as it would require careful measurement. While the chews are effective and have received positive reviews, some users might find the price point relatively high given the 180-count jar. Nonetheless, for pet owners looking for a natural, easy-to-administer supplement to improve their dog's skin and coat health, this product is a strong contender.
