Absolutely appalling. Left my dog un registered despite being registered and having proof of this. Then when successfully "registered" with them and my conact details on there and having a certificate emailed by them of this...I then called the following year to change my address as I had moved to be told the chip was not registered! Even though I have the confirmation certificate from them. So for a whole year my precious dog would not have been able to be traced back to me if he went missing despite me doing everything correctly and them even confirming this. I let this go and updated over the phone to my new address. Then today I log in online to update details to find he is still registered with old details from previous year. This is appalling and if my dog had gone missing I may never have got him back!! My other two dogs are with petlog and in 8 years I have had no issues with petlog at all.
