Hello Aleksandra,
Thank you for your feedback and I am sorry if your dogs are not getting on with the food. I can however confirm that there has not been any changes to the recipe of our Ireland product.
Batches however can differ slightly, think of baking a cake, the ingredients are the same yet sometime the outcome is slightly different. Perhaps the particular batch did not appeal to your dogs as much as a previous one.
A useful tip when it comes to dogs refusing the food is to pop the food in the microwave for 15 seconds, this helps release the fats in the food and makes the food smell more appetising to the dog.
I hope this helps.
Team Happy Dog
