PRICE DOUBLED IN 2 WEEKS
Size: 18 Count (Pack of 1), Size: 18 Count (Pack of 1)
I rescue standard poodles mostly. I also train service dogs. My pack of "poodles" has all sizes and ages. This is not for profit , it is to save lives. Until 2 weeks ago -date now is: 08/17/2022- the price of these were around 20.00. My dogs all loved them. I have a buffet table with lots of storage I use to store the treats and it has room on top for all the treat jars. In the afternoon or evening, they'd get a hard, chewy treat like ears. Standard poodles love to chew . They could finish off one of the ears in minutes. These treats are quiet large and thin. They do smell but they are natural foods. NO WAY can I afford over 40.00 for 18 ears. Did pigs go exttict? Did they quit growing ears? How could They raise the price to cost double the amount? I looked at other ears on Amazon & the other brand i get which starts with a p- has not gone up. Paws- clipping. They have some Bizarre names so guess I'll just double my order for them. I have way too many dogs to give treats to. I want to be fair to all of them. They are my kids & will get the best I can offer. I did wait a few weeks before writting this. I also dropped my Sub & Save with this.
