Product may be good for some dogs

Product may be good for some dogs, but our 40 lb. boxer-pit terrier mix destroyed this toy in minutes.

This may work for some but I had two main problems:

1) it didn't help my dog with anxiety (socializing with new people makes her very shy/anxious) so again it may help some but not all

2) I was very frustrated that they expired about a month after I ordered them.  I never would have ordered the large package.  I think the expiration details should be more obvious.

not really sure about this , my vet said it is a good product and recommended it for my German Shepherd because he has RA real bad. he is 12 1/2 years old but I have not been able to get him to take it , have tired putting other things on it but nothing has worked . Gave it to my daughter in-law for their dog now waiting to see if heir's would take it .

Maybe good for some dogs. Mine barked her way through a refill in less than an hour with no signs of being deterred. We eventually got a zappy collar, which stopped her barking immediately.

I used this product for a couple of months and found NO difference in my dogs. The product isn't cheap so I anticipated it to help keep them calmer.

Didn't work for my two dogs.

I was warned that these only work on about 50% of the dogs that get them. It doesn't seem to help my pooch. He loves the flavor.

Not sure if its the product or our dog. She may be to stressed for something like this to work. We don't see any change in her at all.

Might have benefited the dogs somewhat, but it didn't clear the condition, despite following the directions carefully. In the end, we had to resort to medication.

We were very excited about protecting our leather couches from the dogs jumping and laying all over them, the only thing it seems to have done is given the dogs a new thing to play with. They lay right on top of it or take it off and play with it. This is probably a great product for some dogs, but apparently not our three,

I'm in the middle with my opinion of this product. The price is good and it seems to work. I have tried Pet Armor, Front Line, and (I believe) Advantage. All seemed to work well but the Sentry caused a really strange reaction in one of my dogs. Within an hour of application he became very sensitive to touch and he was really fidgety. He's normally a very passive, lazy dog but when I tried Sentry on him, he couldn't sit still. I tried it twice (a year apart in time) and he had the same reaction, which lasted a couple days. He's a 35 lb beagle/Jack Russell mix. My 15 lb. shih tzu had no reaction at all. So, I'd say it's a good product if your dog doesn't react badly to it.

I was very excited for this item because I have a 4 year old dog and a 1 year old dog.  The two can get very excited before bedtime and I thought this product would calm them down.  After using the product a couple of times, I did notice a difference every other time.  I would spray the liquid onto a treat and then give it to the dog(s).  Sometimes, the dog would clam down and fall asleep but other times it would just be it's usual self.  I actually thought that the product would make the dog very sleepy and then fall asleep.  I guess I was just wrong...

Product is really good; but it doesn't work for one of my dogs; he is very sensitive and affect his nervous system we had have to bring him to the Vet :(. Despite we used out of house I still believe the dispositive was too close for him. We couldn't use it anymore. For your reference our dog is a middle size and 20 pounds.

This is a good maintenance product for older dogs. I would not recommend it as a cure for any existing ailments.

My dog liked this product but to be honest it was not the product that I thought it was as my dog likes the other product better

I'm very concerned that GARLIC is one of the ingredients in these.  I've always read that garlic is BAD for dogs.  I'm going to look for a safer option.

I still have pretty much all of these left in the box. For some reason my dogs will not use them. I even offered them as an alternative to going outside thinking they would prefer that especially when it's cold outside. I even tried training and giving them treats just when they would sit on the pad. Still no luck. Maybe it's just my dogs or my training. Not sure.
