Thanks for all the advice folks. The paste we got from the vet was lax-a-past, but she hates it !! her diet consists of.....various fishy pouches, especially tuna, fresh coley and chicken, senior biscuits, a bowl of squirty cream each night, a few chew sticks and the odd prawn. Doesn't do too bad does she !!
At the moment she's quite regular again, we'll try some of the other laxatives to see if she will take to them and also a little oil in the pouch.
Thanks again.
