Hello again everyone, zappa's being very nice this past weeks, BUT (there is always a but), for some strange reason, this past 3 or 4 days his behaviour has changed. Nothing around him changed, but he is being very nervous and stressed for no apparent reason. He's sleping and suddenly goes outside barking like crazy, then runs inside to sleep again(he never did this before). He's been chewing a lot more lately too, went back to mouthing us, a lot, and being very unsettled . I'm taking him to the vet tomorrow as he is lickin and scratching his but a bit. But on this occasions the vet never has a "response". Zappa just seems to be stresses with no apparent reason. Does this happen (or did it happen) to your pups/dogs? Zappa did mouth us a lot in the past, but with a few time outs he stopped (time outs really work for him), but he came back to it this few days. What happenned??? What can I do???
