My 6 month old labrador puppy has intermittent diarrhea, initially

Resolved Question:

My 6 month old labrador puppy has intermittent diarrhea, initially I went to the vet, got the usual diet prescription everything went great stools firmed up put him back on old diet things okay.
3 weeks later clay coloured soft stools then next day a 'cow pat', so did the home treatment... miss a meal then 2 days boiled rice and little mix of biscuits and meat, stools firmed up great 5 days later back to square one......
He does not eat 'off the lead' but does eat grass in the garden (as do all labs), his diet is still the same as from day one (lamb and rice kibbles with a little bit of tinned meat as a topper).
so I am at a loss as to why this is happening and more to the point how to solve it, I am about to move up to junior kibbles but am worried if it is the kibbles that he is having a problem with.

Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

Can you confirm that he only has loose stools on the original diet?

Is he up to date with his worming?

Did his vet only prescribe a diet when he was seen?

Hi apologies for late response

1. Loose stools appear to be on original diet but this he has been on since we got him at 11 weeks old stools stay solid for about 4-5 days then go loose.

2. Worming treatment given last week

3. Original vet visit vet prescribe course of antibiotics and 3 tins of I/d gastrointestinal health

4. additionally he does not turn away from his food always hungry (like all lab pups)

No worries there,

Now just like people, dogs can have diarrhea like this it can be caused by a range of reasons. With the waxing and waning signs and relapse you have described, I have to say that I'd be less concerned about diet itself (especially if he was fine before as well as he now goes a few days before relapse) and more concerned that this wee lad has an underlying GI agent triggering that loose stool. The reason it may appear to settle on the lighter diet options will be because they are easier to digest even if the gut is compromised. But once the original diet is weaned back, we start to see the compromised gut struggle again.

Now in regards ***** ***** agents, we can see diarrhea with bacterial, viral, parasitic (worms but also protozoa like Giardia, Coccidia, Cryptosporidia, etc), toxins (if he is nibbling something other then grass), nutritional, and general dietary indiscretions type causes ( the last 3 sounding less likely here). Even if he is kept on the lead, while he may not be a foreign body ingestion case, he will still be at risk of exposure to infectious agents if he can even stick his nose into any places another dog may have been (ie grass, plants, etc).

With all this in mind, we can start to narrow the cause of his signs. I am glad to see you have wormed him, since this will rule out some of our potential culprits. As well, if the vet did put him on a broad spectrum antibiotic, this does rule some common bacterial agents out but would still leave a number to consider. Now in regards ***** ***** at this stage, the best next step would be to consider submitting a fecal sample for analysis. This can be submitted directly to your vet before having any revisits and tested for common parasites, protozoa, viruses, and bacteria. This will allow you to pinpoint what is present in the GI and thus be able to target treatment effectively. Depending on the test findings, your vet and yourself could determine if an alternative antibiotic is necessary or if he needs to be treated with anti-protozoal medication to settle this. So, this would be a good option to shed some light on what may be triggering these loose stools (before panicking over dietary allergy issues at his age).

Further to this, I do just want to note that abnormal stools can sometimes linger when a previous infection (that perhaps was addressed by the antibiotics or worming) has disturbed the natural good bacteria population of the gut. Therefore, since he has had some treatments and his signs suggest mild GI digestive compromise, you could consider a probiotic support at this stage. Examples that would be worth using with your lad would be GI microflora supports like Fortiflora (More Info) or Pro-Kolin Enterogenic (More Info). As well, when we have loose stools of this nature, we wouldn't want to necessarily use a traditional anti-diarrheal but could benefit from treatment with a support like Protexin Pro-Fiber (which is available OTC at vet practices; example). This treatment is a probiotic support for the gut bacteria but also has a small dose of Kaolin which can help slow fecal transit and encourage normal stool formation. So, this would be a good option here.

Overall, there can be many triggers for diarrhea of this nature. Since he is young (and doesn't have the reserves of an adult) we do need to be proactive in trying to settle this for him. Therefore, since you have started ruling out common causes for this and seen no resolution, it'd be ideal to consider submitting a fresh fecal sample to the lab to be checked for common parasitic, protozoal and bacterial causes at this stage. Depending on the results, you will be able to treat effectively +/- the above supportive care to settle this for him.

I hope this information is helpful.

If you need any additional information, do not hesitate to ask!

All the best,

Dr. B.
