I got a few tennis balls, a rubber kong which is hollow inside (u get ones which have crushed plastic stuffed inside), a treat dispensing kong but guess what? the little turd doesn't play with anything!! he's been home 2 days & all he does is sleep!! he doesn't have his breakfast or lunch.. has 1 in the evening and 1 at night.. isn't interested in puppy biscuits.. so I have these calcium gnawler bones which he plays with for a little while.. I don't know if everyone's pup is like this but this dude just sleeps & pees & sleeps & poops! he's about 7 weeks old..
He should be sleeping 2/3 of the day till about 3 months. Eating only twice a day doesn't sound like enough, try adding a table spoon of wet with his kibble and soak in some water for 10-15 minutes for breakfast.
Are you putting the toys on the ground and he's ignoring them? or are you handling the toys and he's ignoring them?
Either way he needs a lot more than 2 days to get comfortable in his new home (more like 2 weeks).
Another thing to consider, when I got Barack and took him for his 1st vet visit, it turned out he had an upper respiratory infection (kennel cough). No big deal (Just like having a common cold for us) I got him on his meds, and wiped it out in 2 weeks. During his "cold" though he wasn't very motivated to do anything more than sleep, eat, and poop. He did play with his toys though, just not for very long, as I knew he wasn't feeling his best. BTW I hope he is NOT sick, but I figured I'd put that out there, since I'm not sure whether or not you've done your 1st vet visit or not.
Lastly a word of caution on stuffed toys, eventually they will be able to puncture those and will try to eat the "stuffing", I made this mistake and my boy actually tore off an ear and swallowed it (He did successfully pass it in his stool as it wasn't a very large piece). Safe to say I've phased those toys out completely, Kong inc is making a lot of money off of me lol.
Congratz on the new pup and best of luck!
