I have been giving my senior dog Fiona Canna Pet treats for several months now. She has arthritis and takes carprofen daily prescribed to be taken twice a day. I’m see a huge difference in her after giving her these biscuits. She walks better and seems to feel better too. I really do believe these biscuits are helping her! I won’t stop her meds but I have cut it down to just 1 carprofen daily instead of the prescribed amount. I just don’t want her to be in pain. She is 12 yrs old and I’m so happy I found this product for her!
