the new puppy has been with my mum for about a month, both my mum and dad say they think it is more than playing as they do that but then it seems to go on to a whole level. The original dog is used to a cat and greets other dogs ok. They are hoping that as the puppy gets bigger he will sort of fight back and then they will sort of have a truce???

do you mean the older dog is still only fairly new to it's home? It may not yet feel securely established.
Also how much do they know about how dogs play, Normal dog play can appear extremely rough. do they both seem to be enjoying the interaction or is the younger one trying to get away? If it keeps coming back for more then it is play.
It may need to be interrupted so the baby gets enough rest and the older pup won't have the sense of an adult yet.

Hi,
Is the new puppy female or male? Can I ask the orignal dog is a female Lhasa Apso approximatly 12 months old. Is she spayed? At about 12 months she is due for her second session. This could be just two young dogs playing, it could be dominance, or it could be strong flurting!!!
Before you can change behavour, you have to understand behavour.

Is the puppy yelping during play? She probably would if the older dog was hurting her.
I have my first litter at the moment and Mum would never hurt them, but some visitors are horrified at first when Mum plays with them, and think she is being nasty to them. She isn't, she is just playing, she has excellent bite inhibition and knows not to hurt them. It is how they learn to play with other dogs, not just their litter mates. The play includes their whole heads, legs, ears etc in her mouth at times, and it does look very rough, as I said.
Also, if you have two dogs, one of them has to be dominant, they need to find their pecking order. At first that will probably be the older dog, but they may swap over when the pup gets older.
if your parents fel the pup cannot get any sleep or rest because of the older dogs play, they could crate train her, so when pup is asleep, she can go in the crate with the door shut and the older dog won't be able to wake her.

my first thoughts are puppy playing, they should find their place soon and one will be more dominant than the other once they have sorted it out. Mine are 4 and 14months and they still do it. only get involved if they start fighting properly.
