Those poops look a good size and the blood looks like it arrived in a puddle of wee. This makes me think it is blood in urine. UTIs are not uncommon - we've seen a few in boys and in girls. Sometimes there is a stone and sometimes not. The fact that your x-rays look clear is a good sign. Baytril is the go-to antibiotic for piggies in the UK and has been for longer than I've had pigs so there is some resistance to it. Fortunately there are other ABs available. Just because a pig has a UTI doesn't mean every pee will contain blood. The loxicom is a painkiller and anti-inflammatory, another brand's name is metacam. It's popular with pigs and we've had it with all ours - my boy has been on a similar dose twice daily for over 2 years with his arthritis. I don't worry about that - and it's tasty so they think it's a treat too.
I think in your shoes - well, in your postcode area - I'd be trying to get in to see Ellie...
You said you had Baytril
once a day. Now fair enough it did seem like quite a high dose (I'm assuming it's something standard like 2.5% solution) but we've never had it once a day. We've had between 0.2ml and 0.5ml
twice a day. There's a range of active doses and it depends on other things like piggy's weight. It would work out similar but the point is that pigs have quite a fast metabolism and I'd be a bit concerned that the AB goes in and starts to work but over 24 hours wears off and the residual bacteria start to grow back etc. The next day you're repeating the cycle. That and unlike loxicom, which is sweet, Baytril tastes disgusting and even getting 0.2ml into a resistant piggy can be a challenge so how you managed nearly a ml I can't imagine! Now maybe dosing protocols are changing - I'm not a vet - but I'm just saying that once a day is a bit unusual.
If you have a piggy with UTI you generally see blood in pee, 'chirping' in pain when peeing (or pooping), wet round the bits from dripping urine (either incontinence from inflammation of piggy trying to hold in a painful pee. They sometimes pee more often so you might hear him squeal in the day and at night. They hide away and they are put off eating hay - hence the weight loss. They might still be greedy for veggies but don't be tempted to try and overfeed these to compensate for the weight loss because it can risk bloating them up, and we don't need complications!
When antibiotics work for piggy UTI they usually follow a pattern. The symptoms should subside within the first day or two. Sometimes it's before the end of day 1 if you dose early, sometimes it's overnight. The AB start to work straight away but the inflammation has to subside a bit and the body starts to heal. As a general rule if we've not seen improvement after 3 days I phone my vet and tell them, and they generally tell me to come in and pick up another prescription for a different antibiotic. That being said you should
always complete a course unless the vet tells you not to (like if they switch you to another one). If you have a 5 day course complete it - if you have a 3 week course complete it - because even a few leftover bacteria can rapidly grow into a million once the AB pressure is removed. Finish too soon and you'll be back to square one. But whatever the length of the course, if after 3 days you don't see any difference contact your vet and tell them. Mostly pigs find they feel a bit better and start eating more straight away... sometimes the AB affects their appetite and they need a bit of syringe food support with a bit of probiotic mixed in: all vets should have a type of support food and a probiotic in stock but these can also just be bought online without prescription - it's just food.
My George was peeing blood and crying and we had 5 days of Baytril and an x-ray. It didn't work, and we were switched to Septrin (sometimes called Sulfatrim). George's case was complicated because he is 6 and we saw on the x-ray that he also had a big bladder stone. So we had to decide whether there was no UTI and all this was just down to the stone, or whether to go for the Septrin. I'm so pleased we did - within 24 hours George was feeling
much better, out and about, crying much less frequently and not so loud - unfortunately this particular AB killed his appetite and he had to be on it for a very long time (over two weeks) which was a battle, and he lost a lot of weight. It was actually day 5 when we stopped seeing blood tint to his pee which is a pretty long time in our experience but then he did have the stone. But in the end it worked (and earlier this month George survived the op to remove the stone so he's feeling pretty good). I'd previously had a girl who had a really similar thing - Baytril didn't touch her symptoms, she was also switched to Septrin. Great improvement within a day or so - in fact back to normal by the 3rd morning - but we still finished the course (over two weeks!) and luckily she wasn't affected by it at all and by the end got quite used to the taste (it's not as grim as Baytril)
But within a few days of the course finishing the symptoms returned and my heart sank... another UTI? No, it was the same one coming back, and despite that really long course it still wasn't quite enough so we had another nearly 3 weeks on Septrin (twice a day) and saw exactly the same thing - symptoms improved within a day or so of starting the medicine. But luckily this time when she finally finished her bottle we'd beaten it.
If you have no signs of stones or sludge a UTI is most likely what you're looking at but I'm not sure whether Baytril is the right antibiotic - it will all depend on the timings. If he was still peeing blood and in pain by the third day I'd be hoping for an alternative AB. It's tricky as you can sometimes see a little improvement even if a bug is resistant to an AB it might not be 100% resistant. So it depends on your timings - and whether once-a-day AB is going to be effective even if it's the right choice.
Hence I might be thinking about going to see Ellie...
Hope that helps - and isn't too complicated! Good luck Mr Gilbert x
