Buster wants to sit all the time

[JWM]

Buster is a 4 year old male, who normally acts like the energizer bunny on steroids. Last evening, I put the tube of advantix stuff in three spots on top of his back to treat fleas, lice, ticks. Since this morning, he is lethargic , does not want to move around, always licking towards his tail, does not want to eat or drink, ears and tail are tucked down, moves very quickly a few feet then sits down for long periods of time like a statue. Finally, about an hour ago, I gave him his favorite treat, a raw cut up carrot. He ate that like a starving man and drank at least some water. I washed his back, but don't know if that medication is causing some kind of irratation ? Any ideas? On a side note, what kind of dog food should I be giving him? Also have another male yorkie, 2 and a half, got the same med treatment; but is doing just fine.

One of my pups does the sudden & firm sit when his anal glands are full. I would take your baby to the vet & have his anals checked as they are probably full.

Was this the first time he ever had advantix? I think the first couple of times I gave it to Maggie she acted weird too, now it's all just normal.

Has he had anal gland problems in past?
Has he been treated with this same product previous to this?

If this behavior continues I would call the vet, Buster may be having a reaction to the product.

My male pouts for an entire day after we do flea treatment... So it could be that, but it almost sounds like his anal glands need to be expressed. My male also has problems with his anal glands, and when I notice he starts licking and scooting, I take him into my vet to get them expressed.

Wondering if it might be an allergic reaction?
