How can i stop my dog from messing when we go out please ???

That's jack in the picture on the left

 I would do some research on separation anxiety - and get a crate.

Where does he "live" when you are not home?  My first thought is that he has too much freedom too soon, and needs to be more restricted....  My other first thought is that if he is poohing a lot/very frequently, his diet may need to be looked at.  My OTHER first thought is that maybe he is doing this because he is anxious, because that lessens his control over his bowels. The fact that he was "abandoned" means he is likely to be very stressed at being "abandoned" on a daily basis - he has learned that the human might not come back.

There are lots of things you can do to address his anxiety.   You should keep your comings and goings very low key, BORING even - no major fussing or "goodbyes" - just ignore him when you leave and return.  This is because you don't want him to be in a highly emotional state when you leave, and you don't want him to be anticipating your return either.

Confining him will likely address his anxiety too.  He will have less "decisions" to make while confined, so it will take a load of his shoulders.  Lots of dogs are reassured by it.   Crate training might be worth looking into, but the crate must be introduced kindly and carefully or he may hate it.  It also depends on how long he is left - for the crate to inhibit his toileting it would need to be fairly small and it wouldn't be fair to leave him in a space taht small for a long time.  How long IS he left for?

Other things you can try:

• DAP diffuser
• Rescue Remedy (either a drop right on his tongue shortly before you leave, or a few drops in his drinking water).
  
• Leaving a radio on - a talk station, or something classical will help to soothe him.
• Leaving an old shirt with your scent on in his bed. 
• Puzzle toys/safe chews to keep him busy and distract him while you are out.  Chewing is a stress reliever for dogs! 
• "Practise" leaving several times a day to desensitise him (putting your coat and shoes on, getting your keys, the whole shebang).

The FIRST thing to do is get him checked by a vet, to rule out a medical condition which may be causing the soiling problem, or making it worse.  What are his poos like (if it's not too much of a gross question)?

What do you do when he poohs outdoors?  What kid of reward does he get?  The higher value it is, the more incentive he has to hold on and wait to go outside again to pooh - especially if that's the oNLY time he gets that special treat.  So something real SMELLY and palatable is best - I'm talking liver treats, salmon brownies, small chunks of hot dog sausage.  

What do you do when you find the waste?  Ideally, you should put him out of sight while you clean up, MOVE it outside if possible, then calmly take him out to it on lead and let him see/sniff.  He shouldn't be scolded at all for accidents, but it's useful to let him see that you have MOVED it.

What are you using to clean up with?  Most ordinary cleaners can't get rid of the smell, and dog's noses are incredible!  If he can still smell it, it will encourage him to use the same spot.  

Does he tend to go back to the same area?  If so, you could try moving his bed and food bowls to that place.  Most dogs are clean and won't like to soil the area where they eat and sleep (another reason crating him may help).  BUT - if the problem isn't addressed, he could simply start using another area.  

You could try using an ex-pen (if a crate is not possible for you) to confine him in an easily cleaned area with some paper down.  It won't help to train him, it's a management technique to save your sanity, and at least restrict WHERE he can pooh while you address the issue.

He is very cute - more piccies compulsory

Wow !!!! Many thanks for your advise Chuffy , there's a lot of things to go on there , thanks , yes i will post some pics . By the way his poo is firm and he only goes twice a day (out side that is) but if we go out its more ha ha. Would getting him Castrated help ?   

What is a DAP defuser please ?

Exercise stimulates the bowels, so I'm thinking you need to give him a few extra minutes, maybe even sit down on a bench for a few so "things" get a chance to start moving and he goes OUTside.  Be sure to give heavy duty praise for outside poops.

Thanks Glenmar, but he doesn't have a problem going outside he's very good at that , it's when we go out without him he does it in doors . My wife and I  work during the day so unfortunately he can be left for 8 hours on his own during the week . But he always gets a walk in the morning, midday, evening and just before we go to bed (every day).

Here's an article to get you started in case Jack has SA.  Sounds like that may be the issue.  Please note that crating a dog with SA can make the problem worse and some dogs injure themselves trying to escape the crate.  There are many sources of how to deal with SA.  This article was just one I found with a quick search and glanced at briefly to make sure it offered good advice. :)

By the way his poo is firm and he only goes twice a day (out side that is) but if we go out its more ha ha. Would getting him Castrated help ?   

 I am no expert on nutrition, but if you don't mind telling what you feed him it might be that someone cleverer than me could suggest something more digestible, which would mean he would likely need to poop less.  If he was marking (urine) then castration might possibly help, and there are other reasons you might wish to consider it anyway, but I doubt it will help this particular issue.

 DAP is Dog Appeasing Pheremone.  It's a form of the pheremone which mother dogs give off for their puppies.  It's effective in calming some dogs.  You can get a plug in difuser (works kind of like a plug in air freshener, except we can't smell it) or you can get it in a spray.... you can spray a little on his bed or into his crate.... I've heard of people spraying a bandana for the dog to wear when he goes in the car if he gets stressed by car journeys.  I've also heard that it just plain doesn't seem to work at all on some dogs, but might be worth looking at if some other calming measures don't help.

My point was that when he goes out for his walks, he's getting exercise, and "urging" things to move by that exercise.  So if he poops right after he comes back inside, it's likely that he didn't have time to drop that second load OUTside. Does that make more sense?

Yes it does make sense Glenda thanks,

He has tinned dog food and also biscuits , then he has a bowl of dry food ,we alternate every other day so he gets plenty of rufage in his diet  The brand  is called pedigree , have you heard of it ?? He's quite fussy but he loves that brand
