How can I help my puppy get over his fears?

Your puppy should look to you for guidance when it comes to fearful things. If you are calm and content, your puppy will learn to be less fearful around uncertain things. Never force this acceptance as your pup should always have a choice and it's up to you to guide how he/she chooses ~ by example, encouragement and praise.

If this odd donkey is highly frightening, make it less so by whatever means necessary. Maybe 'donkey' needs time in a box, closet, or left non-inflated for a while to give your pup a chance to make peace with it.

As for sleep and dreaming, this is totally normal behavior and nothing to fret over.

Puppies go through fear stages. This is perfectly normal. Since he has sniffed th donkey once, i would just ignore his fear of it and not worry about it.

Generally speaking you want to encourage (by acting as if the object is the best treat ever) but not force the pup to explore whatever scares him. When it's not possible for pup to explore the object (i.e. bikes or vehicles passing you) teach him to ignore them and keep focus on you by going through some obedience exercises such as sits and downs.

You can increase his confidence by being a good firm and fair leader who uses a balanced training approach including nilif, basic obedience using marker training with the judicious use of proper corrections at the right time. http://leerburg.com/pdf/Ed%20FrawleysPhilosophyonD... http://leerburg.com/pdf/markers-clickers.pdf

Be patient give him a bit of time to live with this inflatable donkey if it doesnt work maby throw that donkey away?

He will never meet an inflatable donkey anywhere else. Just get rid of the donkey and his fears will vanish.

Why force this situation on your poor puppy. It probably smells odd for starters, and isn't like anything he feels he can deal with. Rather than insist he overcomes his fear of this, remove it.

And it could well be he's having nightmares, although we don't know for sure what dogs dream about. For this reason, I always urge my puppy owners to make sure as many of their awake experiences are good ones, so they have no need to be having nightmares.

Don't force him to face the toy that scares him and don't baby him when he acts scared. The former will make him lose trust in you and the latter will make him think it is good to be afraid. Just leave the toy out where he can see it and be around it and then ignore it. Just play with him like normal and don't acknowledge when he is scared by it.

lol my little puppy is afraid of everything and shes scary to and she would also be scared of the inflatable donkey but wat i would do is let tge donkey rub on the puppy to show hes harmless just sit with u the donkey and ur puppy and maybe it wil relax make the monkey rub on u this works for my puppy idk bout urs but u can try

Just be patient and love your puppy
