hi i got a jack russell puppy on monday, he is 8 weeks old today. all the pup does is bite every thing and every one, which is becoming a problem because i dont even want to get him out the cage anymore as all he does is bite weather is a person or a object, he also crys everytime i put him in his cage, however he will go in by himself during the day to play or to sleep but if i put him in it he cries and makes loads of noise. he sleeps in there on a night in the living room and is okay until roughly half 3 then he cries pretty much for the rest of the night. i have tried taking him out the cage and putting him in the bath room which is a big room with his bed and toys but he still cries. someone help mee!!
