Re: oral meds
If I remember correctly he is on Metronidazole? It is HORRID HORRID HORRID tasting unless it's flavoured so he may be reacting to that as well. Even flavoured it is not good.
Get some Hill's A/D from the vet and try syringing just it to him. If necessary, when he is in a ball, squirt a little bit down on his tummy. If you can't get any on his tummy, try putting a bit in front of him when he is standing. Once he gets a taste he should start to become more willing to take the syringe. Once you get him eating the a/d from the syringe, you can then add the meds in with it.
Scruffing works too but remember to support his bum so he isn't hanging by the scruff.
