Abcess -> RI -> mouth rot -> NEXT????

[Denethor]

Hi....
I have "a few" problem with my retic... And I really would like your opinion about them....
Here is his small story.....:
Everything began I think 5 week ago ....
A small abcesss grow in his nose, just between the 2 nostril and one smaller on the head near the eye that apear the day before I went to the vet... That take me 2 ******* week to realise that there were really something wrong with his nose...
the worst... is that I was triing to convince me that it was "normal" I saw it only in comparaison betwen some pictures that I show to someone......( the abcesss is reallly centered so it can almost look normal...)
So I went to the vet... he confirm me that was an abcesss with somes "taking away"?.... He chirurgicaly remove the abcess and prescrive me some Foracin a topic antibiotic... he said me that he doesnt want to give me something like Baytril...he think its too powerfull and risky to give something like that to my baby retik (5 feet..) ...
He also said that I didnt need to give him something more powerfull in injection because it was near the skin and if I was keeping the wound open with a 50/50 of peroxid and betadine that would do the same job....
It take 3 ***** week to totaly get rid of the abcess... and now since monday I leave the cicatrisation process to himself ...
BUT..... a few day before that........ Sauron begin to do some kinnnd of respiratory infection.... there was bubble in one of his nostril.... and kind of bubling saliva in his mouth.... the vet take some mucous from the nostril to analyze them.... I call him back this morning... and he confirm that there are bacteria and he gonna prescrive me an other antibiotic.... I only have a rv with him tomorow night ...
But thats not all!
Yesterday night......... I realise that he develop something like mouth rot also...........
Im really desesperate..........
Im gonna try that antibiotic........ and if that dont work you can be sure that im gonna change of vet...... but he look to know what he is doing despite everything....
I just want to know what your thinking about all that please...
Do you thing what my vet is doing sound ok? or he is totaly wrong since the begining.... there is definitivelly something wrong somewhere........ or im just reallly not lucky?
Thanks..
cya
