Firstly - re the baytril dosage - I would need to know their weights to fully comment on effective dosage please? But as your hubby is a pharmacist, hopefully the following info will help.
According to the BSAVA Small Animal Formulary, 2007 (I don;t have a later version ) the recommended oral dose range for baytril at that time in rabbits was 10-30mg/kg per 24hr and in rats was 5-10mg/kg every 12hours
Most cavy savvy vets opt for the rabbit dose rather than the rat dose because guinea pigs have a fast metabolism.
So for 2.5% solution (the normal prescription) this equates to 25mg/ml.
However on some RARE occasions vets have prescribed the 10% solution which would equate to a concentration of 100mg/ml.
As your pigs are youngsters I am going to assume they weigh 500g (and that hubby can work out the dose range from there dependent upon their actual weights)
For a 500g pig - an effective baytril dose using the LOWEST rabbit range (10mg/kg once daily) would be:
0.2ml of 2.5% once daily or 0.125ml twice daily
and
0.05ml once daily or 0.025ml twice daily for 10%:
It therefore appears to me your guinea piggies are on a very "conservative" dosage. If my maths adds up then I think you need to consider finding a more cavy-savvy vet!
Secondly - I would like to make it very clear from my long experience of dealing with URI's in MANY guinea pigs that the ONLY time me and my vets have PTS a URI piggie is one who developed a very sudden infection (we think viral rather than bacterial) that produced so much fluid in their lungs literally overnight and to such an extent that a diuretic such as frusemide would not help quickly enough and it was kinder to put the piggie to sleep (who literally has fluid dribbling out of his nose and mouth, was gasping for breath and couldn't even swallow).
Prompt prescription of antibiotics, willingness to advise/prescribe supportive meds such as gut stimulants (emeprid/metoclopromide, zantac and preferably also cisapride) , diuretics (fruseamide) and anti-mucolytics (bi-solven) by the vet as well as provision of supportive syringe feeding everry 4 hrs by the slave if necessary can/are all part of "a successful care package" to successfully cure a URI in piggies.
Thirdly - we have discovered over the years (from microbial cultures of all my own pigs) that two of the main "URI" bugs (Staph and Strep) have developed resistance to baytril and septrin. Our first port of call now with my piggies is Doxycycline - this is also important because of the fourth point below.
Fourthly - it would appear from recent posts on this forum that there may be a possible Chlamydia issue at an organisation(s) that supplies a certain leading pet store with baby guinea pigs. This causes respiratory symptoms and eye issues. If your piggies have a chlamydia infection, then baytril will not work so Doxycycline should be considered instead.
