Hi. Well my Dustie now 6 months old is just the same..will eat anything and everything that moves..flies or looks like it will fit in his mouth...
But I have a patio area which he goes out on where there aren't any plants he can digest. He hasn't yet had access to the rest of my garden..as I am a bit worried about some plants and I just know he will make a beeline for them all.
Have you anywhere you can let your pup out without being near to the plants? If not..then I am sure someone on here will tell you what to watch out for in the garden... Sorry not to be of more help...but if I were you I would keep taking things out of the pups mouth with a stern "No" letting him know that you disapprove ..
Chrisann....
