This might seem like an odd question, but my dog is currently on an SSRI for his high anxiety. Last week his dose (Paxil) was upped from 20 mg daily to 25 mg daily. Is this something that would still take 4-6 weeks before results can be seen, or is it possible to see results even just a week later? I'm wondering because he does seem to be doing better but I don't know if that's due to something else entirely or if I'm just seeing things.
